Today available to most drivers. For example, technological and functional complexes of signaling installations are not so expensive that they can save on them. In addition, you can purchase individual components that regulate access to the machine and its critical mechanisms. These include the smart car key, thanks to which the remote unlocking of the locking mechanism is implemented. In particular, it can be a door, a power unit lock, a stopper with electronic control, constipation luggage compartment or gearboxes.
General information about car keyless entry
This is a high-tech system for providing a security mechanism with the possibility of remote intelligent control. In normal mode, factory complexes of this type operate according to the program scheme. That is, the lock itself functions in conjunction with or a special controller. In other words, keyless entry to a car or immobilizer is not just a separate device for contactless entry into a car. This is often a security mechanized complex, as well as a central unit for receiving a signal from a key. The simplest standard devices suggest the possibility of locking the electric starter or engine through an electronic system. Separate models involve more radical solutions - in particular, a scheme can be implemented in which the electrical circuit connections to the power unit. Accordingly, by means of a key, an artificially open circuit is restored.
The principle of operation of the immobilizer
The use of various mechanisms for blocking the functional parts of a car is common in many anti-theft complexes. This effective remedy preventing attempts to start the movement of the car without the knowledge of the car owner. But systems keyless entry have their own characteristics. The main one is the principle of operation of the Smart Key system key itself, which involves the intelligent functioning of data reading mechanisms. In particular, recognition is provided by modern electromagnetic chips and actions, information from which is sent via an antenna to the transponder of the control unit. Such a complex key matching algorithm prevents attempts and electronic hacking of the security system. Moreover, the aspect of mechanical anti-theft protection, which is realized not only by stopping the engine function. Typically, experts recommend using at least three barrier sites, among which power unit, door and gearbox.
System functionality
Almost all keyless entry kits perform the basic functions of opening and closing doors, as well as starting and stopping the engine. Another thing is that the parameters of work with different parts of the car can change. For example, to activate the power unit, only a keyless entry button is required, which will work at a considerable distance, and the owner will be able to enter the salon only at a distance of 1-2 m after reading the information from the RFID key card. And vice versa, reverse actions with blocking of all serviced mechanisms can be carried out in automatic order after deleting a user with a programmable key. It is important to consider that after some time, with complete inactivity, the system can also automatically lock the same doors. But this function is initially set parameters - including the timeout. As for the additional option, the system can be combined with car alarms and their individual components, including sensors, trunk, etc.
System management
All operations are performed only with the original key, which is included in the system. The standard control algorithm involves the use of an electronic code key. But there are also devices that have the ability to manual dialing code. IN this case the owner does not need to use the buttons remote control- he must insert the key into the appropriate slot, after which the system will automatically read the information by the immobilizer system. At successful verification keyless entry will work, unlocking all locks covered by the system. There are also devices that are complicated in the privacy parameter, in which even before electronic reading of information, it may be necessary to pre-set a user code that opens access to the immobilizer system itself.
Immobilizer Vulnerabilities
Unfortunately, even such systems do not guarantee the absolute safety of the car against the actions of intruders. There are several ways to bypass the security complex. First of all, each keyless access kit provides through which, using special equipment, the operator can enter the equipment into emergency mode. Further, the same engine can be given any executive command. This bypass method is theoretically possible, but in practice only a highly qualified specialist can perform it. In addition, you can fake an intelligent car key, and the information for this is recorded even at a distance. Special photographic devices are capable of scanning the device, making an electronic impression of it. And this is not to mention the fact that any work with a car in a car service center will inevitably require the provision of the same key to employees.
Smart Key System Manufacturers
In this segment, quite attractive offers are developed by car manufacturers themselves. This is the case when standard equipment turns out to be more technologically advanced than individual models. The advanced solutions in this area include devices implemented in Toyota Verso, WV Touareg and BMW 6 Ser. A less premium, but very solid immobilizer is offered in the model. At the same time, independent manufacturers of electronic systems for cars produce noteworthy devices. Thus, experts highly appreciate the keyless entry alarm in the BP-05 modification from StarLine. Good feedback also receives the multifunctional development of Smart Start Galaxy, covering a wide range of systems for security control. But, in choosing such devices, one should not forget about the price tag, which is also not distinguished by modesty.
How much does a keyless entry system cost?
The most primitive systems of this type from Chinese market can be purchased for 1.5-2 thousand rubles. These are models with minimal security features and dubious reliability. Even if you plan to purchase a device entry level without any special technological frills, it is recommended to turn to models with a price tag of at least 3 thousand. In this segment, by the way, some StarLine kits are also presented. More advanced structurally and functionally keyless access with the ability to automatic diagnostics and compatibility with alarms will cost 5-7 thousand rubles.
Keyless Entry Benefits
Among the primary advantages of the device is a combination of ease of use and a high degree of reliability. Nevertheless, a multifactorial barrier to the actions of an intruder, which affects both the power unit and external locking mechanisms, provides a high degree of security. In addition, the functionality of such devices is also noted. The fact is that keyless entry with an immobilizer is rarely used alone. Most often, the device is introduced into the general complex of security or alarm systems. This means that from the same smart key, the user gets the ability to control other functions, except for protective ones.
Keyless Entry Disadvantages
Of course the most weakness refers to the vulnerabilities of this technology. But it is important to understand that it is in practice that hacks of intellectual protection are extremely rare. Moreover, the very idea of the same diagnostic nest is due to the need to create an opportunity for the user himself to bypass the system when it is completely blocked. In addition, keyless entry can cause some problems in the implementation of a separate control system. The fact is that the device involves close interaction with the central control unit. This nuance means providing a high load on the local power grid, and can also cause problems with the operation of other electronics.
Installation
How is keyless entry installed? Installation operations consist of two stages - the implementation of electrical wiring and the mechanical installation of equipment. As for the first part, then from the cigarette lighter or battery pack power lines are laid to security blocking systems. Next, the mechanical installation of the blockers is already carried out, and, if necessary, the installation of special sensors, which will also participate in the process of automated unlocking. In turn, the smart key is connected via a special wireless interface to the central control unit. A separate controller can also be used for this task.
Conclusion
Keyless access, of course, can only be called conditionally. The difference of this system from the usual key is caused only by the change of the physical principle of operation to the electronic one. Go to electronic means management and control of security systems has been going on for a long time and the spread of such devices is quite a logical phenomenon. In addition to the protective properties, the smart key is also valued for its ergonomics when working with locking mechanisms. If conventional alarms are almost entirely based on electronics, without the advantages of physical interlocks, then in this case the advantages of the two concepts are combined. The immobilizer user can count on the convenience of using the smart key, and on the mechanical protection of the vehicle's blockers.
At school, I was taught that under communism all sorts of locks and keys would become unnecessary by definition. Homo sapiens will be so conscious that it would never occur to him to use what is intended for another. And although the construction of communism has been stopped (or temporarily suspended), the keys are slowly beginning to fade into history. But isn't it too early?
Mercedes was the first to acquire a serial keyless access system to a car back in the last century, today almost everyone uses a similar solution. The names of the systems and the specific circuitry may vary - Hands Free, KeyCard, Comfort Access ... But the main thing is that manufacturers have already accustomed us to this convenient and simple access system: I went to the car, opened the door, sat down, pressed the start button - and forward. The only requirement is to have proximity key, the so-called label. Without her, no way. Or are there options?
Rental without demand
Unfortunately, there are options. Recall that a label is such a microcircuit with an antenna. The car emits a modulated high-frequency signal of high duty cycle, and the tag picks it up at a distance of no more than a couple of meters. Having identified her car, she sends a signal to the on-board anti-theft system to unlock access to the passenger compartment and allow the engine to start. The exchange of information usually takes place at frequencies from 125 kHz to 2.4 GHz. The ignition lock, of course, is absent: to start the engine, just press the Start button. Leaving the car, the owner simply slams the door, after which he touches the button on the door handle. That's it, the car is locked and armed! Now we remember what a repeater is: it is a radio transceiver device located at intermediate points of radio communication lines, which amplifies the received signals and transmits them further. For example, a television signal that brings enlightenment to a distant mountain village. If the repeater amplifies the signal from the tag, then the machine will begin to obey not only its owner, but also ... the owner of the repeater!
Got the idea? No? Then here's a crime scenario for you.
They wrote the crime
Making a repeater compact enough to hide in a small bag or briefcase is not difficult today. And let the label lie in the owner's pocket, no one is going to steal it. It is enough for a criminal with a repeater to just stay a couple of tens of seconds next to the owner of the car. The assistant will do the rest.
An ideal place for a crime is sites near large supermarkets and entertainment centers. Cars - the sea, people - the ocean. The owner closes the car and goes shopping, followed a couple of meters away by a hijacker with a repeater in his bag. As soon as they are removed at a respectful distance from the car, the offender gives a signal to his colleague - for example, calls him on his mobile phone. He opens the car in one movement with the help of the second repeater unit, camouflaged, for example, under a conventional walkie-talkie, starts the engine and leaves. Communication with a real label is no longer needed - the car, having lost it, will no longer stall.
And what is left in the pocket of the real owner, in fact, turns into a black mark for him, on which is written: "Sentenced to confiscate the vehicle."
How to protect your car with a contactless access system from thieves?
Unfortunately, today in Russia, as well as throughout the world, the number is growing. How, then, can car owners protect their cars from intruders who have long used radio equipment to steal, which can easily bypass even the latest innovative car security systems?
The theft of cars equipped with a keyless entry system (Keyless Go) is a relatively new phenomenon. But despite this number of car thefts with contactless system access is growing exponentially. The most interesting thing is that attackers easily steal even new and expensive premium cars, which, according to automakers, are equipped with the most advanced anti-theft technologies. For example, watch a fresh video where you can see how criminals are.
By the way, the growth of car thefts around the world (in our country there has also been an increase in car thefts) is primarily due to the fact that every year an increasing number of vehicles are equipped with a comfort access system that uses a contactless key fob.
Why, then, modern cars equipped with the most innovative security systems have become much more vulnerable than their predecessors? The race of manufacturers is to blame for everything. After all, we can agree that the keyless entry system is very convenient, it allows you to disarm the car without using a key and without pressing the buttons on the key fob.
What happens when a car is stolen with a Keyless Go system?
Criminals use the method of theft without a key to steal a car, i.e. by relaying the signal from your proximity key to a special radio that the intruder keeps next to your car door.
In principle, this type of theft is based. At the moment, this electronic equipment can be easily found on the Internet and purchased.
How do hijackers who have purchased such a repeater act? First of all and most often they look for the so-called "victim" near residential buildings, where cars are usually parked at night. Next, the criminals check all cars with one goal, to find a car equipped with such a keyless entry system. For more information about the technology of stealing cars with keyless entry to the salon,.
To do this is quite simple. The point here is this. Most are equipped with a start/stop engine start button. You understand, it takes a few seconds to find out if your car is equipped with such a keyless entry system.
Further, the criminals are divided. One with the radio remains at the car, and the other goes to residential building for one purpose, to pick up the signal of your proximity key, which constantly broadcasts a low-power radio signal.
As a rule, most of the hijackers first go with their radio under the windows or balconies of residential buildings. After all, many of us leave the keys to the car in the bedroom, the windows of which overlook the courtyard where the car is parked. Thus, criminals have a chance to catch a signal under your windows. Unless of course you live very high.
Also, criminals can enter the entrance in order to fix the same radio signal of a contactless key fob that is distributed in front of the door of the apartment. Unfortunately, that's how it is, through the door. Many car owners put the key on the bedside table or on a shelf in the corridor of their apartment, in front of the front door.
Having caught the radio signal of the contactless key fob, the car thief's radio receiver amplifies the signal with the help of a radio amplifier and transmits it further to the radio via a special channel. And as you probably guessed, this radio signal is sent to the street, where another hijacker is standing next to the car, holding a special radio repeater in his hands, which, receiving the radio signal from the key fob, on which it is received by the car's security system.
As a result, the car's security system will recognize the original car key and naturally disarm the car.
The second and most common place for car thefts with keyless entry systems is the parking lot of shopping malls and supermarkets. In this case, one of the criminals goes right behind the owner of the car, in order to catch the radio signal of a contactless key fob. The second hijacker is already at the car and is waiting for the transmission of the desired signal in order to open the car. After all, having got directly into the car, the attacker only has to press the stop / start button and start the engine, because the security system has already disarmed the car.
If everything is explained in a simple way, then you can say this. The radio itself, which the thief holds next to the victim's car, specifically becomes the car's native key and actually deceives him. Indeed, in this case, the car alarm thinks that the original owner key is located next to it.
The entire hijacking process can take as little as 60 seconds. This type of hijacking is one of the fastest and easiest for car thieves, since in this case they do not have to hack door locks and break the ignition lock, but simply use special equipment to deceive the immobilizer. It is noteworthy that the attackers themselves in this case have a small risk, since such a hijacking occurs in complete silence and without the risk of an alarm being triggered.
How to avoid car theft with the Keyless Go system?
This type of theft can scare any car owner with a contactless car access system. After all, this is a high-tech type of theft from which it seems very difficult or almost impossible to defend yourself, unless, of course, you equip the car additional types security systems. But in fact, not everything is so sad. from contactless hacking is always there. All of them are not expensive and low-cost, in contrast to the installation of additional mechanical security complexes or installation of an additional second alarm.
Protect your car key itself
To protect yourself as much as possible from this type of theft, you must directly, which will not allow the hijackers to catch the radio signal of your proximity key.
Firstly, keep the contactless car key away from the front door and away from the windows, especially if the windows of your apartment (house) overlook the courtyard where your car is parked.
This will allow you to minimize the chance that the thieves will pick up the radio signal and amplify it, thus transmitting the signal to the radio next to the car.
Secondly, you can purchase a special case, Faraday bag or car key storage box that suppresses the radio signal transmitted by the proximity key.
Including you can just use foil and wrap a key in it, which can also drown out the radio signal. True, we want to note that all these things do not guarantee 100% suppression of the radio signal.
On the network you can find and see with your own eyes a lot of experiments, where many methods of suppressing the key's radio signal do not work. In order to be sure, for example, in the special case you use for a contactless key or in the Faraday package, which, by their principle, should block the radio signal of the key fob, you need to go to the car and just check if the car’s security system recognizes the key. Do some tests. If the car does not unlock the doors, then it does not pass through protective layer case or package.
Can the Keyless Go be disabled?
Yes, you can. Many vehicles have the ability to disable the Keyless Go system, which gives you comfortable access to the interior without using a key. To do this, refer to the vehicle owner's manual or technical Center, where specialists will disable your keyless car access system. Unfortunately, it is not possible to disable the Keyless Go system in every car, and not every one of them will be so easy to do. However, in most vehicles, this can still be done.
Mechanical car protection
You can also purchase additional security system. For example best solution there will be a mechanical protection installation for you - i.e. lock on the steering wheel, on the gearbox lock, on the brake pedal lock, etc. etc. Including you can buy a special clamp for wheels.
By installing mechanical protection on the car and thereby create difficulties for stealing your car. After all, having gained access to the car interior with the help of special equipment, they, i.e. hijackers will face mechanical protection, which will take extra time to break. Most likely, in this case, the hijackers simply retreat, as new and unjustified risks appear for them.
How else can you protect your car with Keyless Go?
You yourself understand that 100% protection against theft does not exist (no matter what you were promised and told in various companies involved in the installation of anti-theft systems). The main thing to remember is that the risk of car theft is always present, even when it is literally full of various security and sophisticated equipment.
After all, the task of every car owner is simply to reduce the risk of theft itself, thereby providing for all possible ways protect your car from intruders.
First, we advise you to always be vigilant from the very beginning. When you get out of the car and go shopping, for example, in a supermarket, be sure to remember that in order to steal your car, criminals need to catch the signal from your key. And in this case, there must be a person next to you, who is usually disguised in a backpack or sports bag. Nevertheless, in any case, the person next to you will be very suspicious and somewhat insecure, you can easily notice this.
Secondly, we advise you to install an alarm in your car with satellite system tracking and monitoring system using cellular communication. Yes, many of you may object that such systems are also easily and quite skillfully bypassed by the attackers themselves, while using other and more expensive equipment. But still, in this way you in any case increase the chances for yourself that your car will not be stolen.
Why aren't automakers doing anything about Keyless Go technology?
There may be a misconception that automakers deliberately do nothing and do not improve the technology of keyless comfort access to the car. After all, they know about the massive theft of cars with this system around the world.
But in fact, and despite the fact that the problem of such theft appeared quite a long time ago, many automotive companies for several years they have been developing new Keyless Go systems with the sole purpose of preventing hijackers from using the simplest equipment to relay the signal of a contactless key fob.
For example. Many car companies have started experimenting with frequency, and some have decided to equip cars with the latest software, which is based on the technology of "artificial intelligence", which itself is able to distinguish the original key from the hijackers' relay.
Unfortunately, such innovations by automakers are not cheap and, as a rule, they appear only on expensive ones. premium cars. Although not a fact, if you return to the beginning of the article and watch the video, you will immediately understand that even a new and very dear Mercedes can be easily hijacked using special radio equipment. And this is all taking into account the fact that Mercedes company time and again on the network and on television touted its latest security system.
Thus, it can be stated that today the problem with the system of contactless access to the car has not yet been solved, especially on a global scale. Indeed, in most cheap cars today installed standard keyless system Go, which is easily hacked even by not very expensive hardware. I would also like to point out that last years radio equipment used by car thieves has become significantly cheaper, it has become easily available for purchase on the network.
And if this is so, then every car with a keyless entry system is today in a big risk zone. Therefore, each owner of such a car must necessarily and in advance make additional protection for your property, do not rely on the vaunted full-time security system, which the manager at the car dealership has probably already spoken very well of more than once. Remember that the Keyless Go system seriously vulnerable !!!
An intelligent car access system (other names - keyless access, smart key, smart key) is an electronic system that is designed to make life easier for an ordinary car owner, it identifies the owner by the answer that is registered in in electronic format on the key, if it is correct, the door is unlocked, you just need to touch the handle, the engine starts with just one press of a special button. The electronic key, as well as the usual one, fits in your pocket without any problems.
The first keyless entry system was used in cars from German company Mercedes-Benz over 10 years ago. Today, the intelligent access system can be offered in standard equipment(but, more often as an option).
For different car manufacturers, the smart key system may have its own unique name, for example:
- Advanced Key-Audi;
- Comfort Access - BMW;
- Keyless Go-Mercedes-Benz;
- Keyless Entry - Kia;
- Advanced Keyless & Start System - Mazda;
- FastKey-Mitsubishi;
- Hands Free KeyCard - Renault;
- Intelligent Key - Nissan;
- Smart Key System - Toyota;
- Keyless Drive - Volvo.
The design of the intelligent access system includes antennas, a transponder, touch sensors, an engine start button, the electronic unit management.
The transponder directly identifies the owner. This node is a microchip with an antenna that can be installed in the place where the physical key of the car would be installed or run as a separate plastic card. The most common option is to combine a transponder and a physical key. This solution is one of the most reliable.
The antenna provides radio communication between the machine and the electronic key. Full signal coverage - up to 1.5 m, depending on the type of model.
Photo of the handle touch sensor car door from the Audi A5 S-Line
Touch sensors can be installed in outer handle doors. Touch recognition occurs due to a change in capacitance.
The engine is started by pressing the "Start" button, which is placed in the place where the traditional ignition switch should be installed. Sometimes, instead of a button, a switch may be installed.
Electronic control unit. This node provides a direct implementation of the intelligent access function, it also starts the engine without a key. Control units and central locking interact with the engine management system.
Intelligent car access system: how it works
As soon as you touch the door handle, the sensor will work, then the information is transmitted to the control units. Then the signal goes to electronic key, it recognizes the position relative to the auto. The signal is transmitted to the antenna, then it is processed. If the data matches, then the door opens. Either a microchip or a special magnetized surface is responsible for the safety of data; it is almost impossible to fake a device.
Starting the motor is made by pressing one pressing of the button. Visually, this is no different from starting the engine with a key. However, the startup process is different. The signal is sent to the control units, then through the antenna to the electronic key. It recognizes the position inside the car and transmits it to the central locking antenna, and also unlocks the anti-theft alarm. Anti-theft locks are disabled. The system control unit sends a request to the motor control units and if the motor is ready to start, then it starts.
When the car stops and the driver leaves the car, the doors are automatically locked and the anti-theft alarm is activated. Depending on the system model, blocking can be done different ways: Pressing the button on the door, touching the door or exiting the car. Typically, an intelligent vehicle access system can combine several locking and locking methods.
In some highly advanced systems, system settings can be made using the smart key. When the machine is opened, the position is set driver's seat, exterior mirror, temperature regime and other systems. On the key, with such a wide functionality, touch or voice control can be located, advanced systems cost 50-100% more.
Owners of modern cars have the opportunity to get into their car using keyless entry. As the name implies, with the help of this system, the car is made available to the owner without using a key, in the usual sense of that. So how does this system work? And how can you protect your car when it's so easy to access?
How did the idea come about?
The ability to introduce keyless entry into a car, thereby eliminating the key as a necessary accessory for a motorist, attracted automotive engineers And ordinary motorists more than fifty years ago. Those who are older should remember how back in the days of the USSR, car lovers tried to install on their own hands on domestic cars starter push button "START/STOP" instead of a conventional ignition lock.
Interesting to know! South African law allows the use of any degree of self-defense in cases of threat to the life or property of the owner. The same applies to cars. To protect the car from theft, you can place traps around it, use shockers and even flamethrowers.
But such tuning did not solve the problem. complete failure from car keys, but only reduced their number. After all whole line cars Soviet car industry could not be fully operated without two different keys: one opened driver's door and the trunk, the second one started the car.
Automotive manufacturers, unlike garage craftsmen, approached the problem more carefully. They tried to combine the ease of use of the system with the guarantee of the safety of the car, in cases of unauthorized entry by third parties or interested intruders. Of course, such systems were installed only on concept cars.
Then every automaker tried to jump out of his skin in order to solve the task as creatively as possible, and most importantly, conveniently and efficiently. Even an “intelligent system” was created - a system that included fingerprint scanners, face identification and more. But such devices were very complex and very expensive to put into practice. mass production. And only when they appeared reliable systems, identifying the radio signal with a floating key, which was transmitted over a closed channel, it turned out to design the desired. And so the system of keyless access to the car was born.
One of the first vehicles on which such equipment was installed was mercedes benz W220, which was produced in the mid-nineties of the last century. Only then were the engineers able to eliminate the main technical difficulties, thereby ensuring the effective functioning of the system throughout the entire operational life of the vehicle.
Interesting! Two negligent intruders from America stole a car, but left behind a twenty-kilometer trail of donuts that fell out of the trunk of a car. According to him, the police quickly found them.
How does a car keyless entry system work?
The principle of operation of this system is both simple, but at the same time complex in terms of technical implementation. In fact, this system still assumes the presence of a key, but it can be performed in various variations, and not in the usual understanding of the key as such. A special electronic unit is mounted in this key. With its help, the owner interacts with the car at a short distance.
How does modern car keyless entry work? When the owner of the car approaches it at a certain distance, the electronics recognize the smart key code and remove the protection by opening the door locks. Once in the car, the driver will only need to press the start button and the engine will start. When the car owner leaves the car, moving a certain distance, the electronics loses the signal and automatically locks all doors, and also disconnects all electrical circuits.
As you already understood, the principle of operation of this intelligent system quite simple. And, of course, many readers familiar with the basics of electronics will wonder reasonable question regarding the appearance of such systems only twenty years ago, and not even earlier. The answer lies in the main technical challenge that prototyping developers faced a few decades ago - security. vehicle. The car must recognize only the owner's key, remaining inaccessible to other intruders.
First experiences with similar systems identified security gaps. The key signal could be easily intercepted and re-projected to the hijacker, who had a portable radio receiver and transmitter. It would be logical to equip the system with cryptoprotection, but then the code would be the same, which would also expose the car to the risk of theft.
The panacea for these troubles was the emergence of digital technologies and, subsequently, complex coding based on them. And so it appeared a system of interaction between a car and a smart key based on a floating code. In this interaction, a plural numeric value is sent. And at the preliminary stage of signal reception, an arbitrary code variant is generated from all available variants. That is, if the scammer even intercepts the sent code, he will not be able to use it, since in the next steps there will be an instant generation of new numerical values electronic code. Due to the multiplicity options, the chance that the attacker will "hit the sky with his finger" is reduced to zero.
Types of keyless systems
Before moving on to enumeration possible types of these systems, we want to note that their differences, first of all, lie in their form, and not in content. All smart keyless entry systems work on a similar principle. The only difference is the execution of the smart key itself and how it is used.
For example, some keyless systems on cars that rolled off the assembly line in the late 90s and early 2000s have an additional folding key that is used “at random”. Yes, the first time automotive manufacturers reinsured the owners against the possibility of an unforeseen failure in electronic system. Today there are no such options.
We have mentioned the smart key more than once in the article, but we did not really explain what it is. Today it can be a key fob or a smart card. In the first case, it can also serve as a remote start of the car. When the driver gets into his car, he pushes the smart key into the slot specially designed for him, activating the ignition system. Using a smart card is somewhat different. It does not need to be put anywhere, inserted, carried anywhere, etc., it is simply with the owner: in a pocket, in a purse, in a business card holder, wherever it is more convenient. Everything is simple here. It is enough to approach the car, and the doors will unlock themselves. You just have to sit behind the wheel and press the "START" button.
Interesting! One hijacker survived a serious shock. He illegally took possession of a van that belonged to some professional pranksters. When he got into the car and drove off, he noticed bloodied corpses. He was very frightened and went to the nearest police station. But in the van were only mannequins of people made up for Halloween.
An interesting implementation of the smart key has been developed by Jaguar in her latest sports crossover F-pace. Here, a wristband acts as an identifier, which does not need batteries, and is made of waterproof material.
Of course, in terms of its convenience, this development is ahead of many, because the risk of losing a smart key is minimized. The bracelet sits firmly on the wrist, unlike the same key fob or card, which can simply be forgotten or lost somewhere. Most likely, this decision will be "licked off" by other manufacturing companies. It may even be possible to integrate chips into watches or even jewelry, but this is only a matter of technological progress.
Advantages and disadvantages
Many motorists ask themselves how safe is keyless entry in a car and if it has obvious pros, then there must be cons. After all, there is such a pattern: the problems that arise with any device are directly proportional to the complexity of its technological implementation.
Recently, the climate in our country is joking with us in earnest. Therefore, it would be quite logical to think about how the keyless entry system will behave in extreme heat and prickly frosts. From experience service centers, you can safely refute the fears of car owners that arise on this occasion. The percentage of breakdowns of this system from the total number of all that occur in the car is very small.
As a theft protection, the keyless system is very reliable, but only if it is used in collaboration with others. anti-theft systems. Although there is already a built-in immobilizer function, which is quite enough for basic protection of the car from theft.
But friends, don't be fooled. Difficulties with keyless access to the car can still arise. Firstly, if the smart key is lost, then you will not get into the car just like that, but this is not so bad. You won't even turn it on. It will be possible to unlock and register a new key only in the official dealer center . It’s not even worth poking into garage workshops, it’s unlikely that anyone will undertake such a thing. You can, of course, make a duplicate when buying, but you should store it very carefully.
It is important to know! If you lose your key, rewrite the codes immediately. Someone who saw you getting into your car might recognize your smart key. You will have one more task. But already with an asterisk - find your car.
Keyless access to the car, development prospects
What is keyless access to a car, we explained in detail, but there is one more interesting assumption left. At first glance, you might think that there is nowhere to refine these systems, since at this stage they are perfect.
In some expensive models cars, smart keyless entry systems do not only what we talked about above, but also restore settings driver's seat, up to the inclusion of a favorite track when the owner gets into the car. But progress is constantly moving forward, and car companies are working closely with electronics suppliers, scouting ways further development keyless systems.
One of the current and priority areas today is the integration of an intelligent system with smartphones. But here again a long-standing problem emerges - the danger of outside interference. also in soon there may be systems that recognize the owner's fingerprints. They will be integrated into the door handle.
But there are certain factors that can complicate the procedure for this identification: pollution car body or hands of the owner, extreme increase or decrease in temperatures, rain and so on. Therefore, if one is engaged in the development of identification systems, then according to more general visual or voice signs.
In addition, if all kinds of various “chips” are introduced into keyless access, then cars will cost prohibitive money. A striking example is the Audi A8 with a fingerprint detector on the door handles.
