In fact, every modern car released after 1995 has a chip key. This chip is called immobilizer. Its purpose is to save a special code that feeds the command to the ignition control unit - and the car will start only if the codes from the immobilizer and the chip in the key will coincide. About this further in the article.

Chip-key car, what is it and how is it arranged?

The concept of "immobilizer" appeared quite recently, together with modern electrical systems in foreign-made cars. This device is intended to prevent the hijacking of the vehicle, blocking the operation of the engine and the ignition by the rupture in the electrical circuit. Usually, the chip key consists of the following elements: a control unit transmitting pulses to turn on the ignition and operation of a motor, an immobilizer that prevents the start of the car in the event of a power break, and a specially saved code.

At first glance, this system is complex, but is actually quite simple, but before turning to masters or to the service for the manufacture of a chip-key duplicate, it is necessary to take into account the specifics of a particular chip key for a specific vehicle model.

User reviews about the advantages and minuses chip keys

According to user reviews, chipped keys, in comparison with conventional keys, provide a high level of security, because not only open and closed the doors, but also protect the car from the hijacking. In addition, the unique design of the chip key allows you to control the alarm system and run the motor at a distance.

However, there are negative sides. If the key with the chip is lost, it is very difficult to get into the TC cabin, when with the loss of a simple key, you can climb into the salon without hacking doors, glass or castle. However, while the risk of a car of the car, which opens with a regular key, is significantly increased.

Chipped keys necessarily require configuration of performance and adaptation, and conventional keys can be applied immediately. When breakdown or loss with a key with a chip, you need to use the serial number of this device. That is why any car owner must store a license plate.

Car keys that have a built-in chip are characterized by high sensitivity to the effect of sunlight, high humidity, highly low or highly high temperatures. They also react poorly to electromagnetic waves or mechanical damage.

Why do you need to have a duplicate car chip key?

If for certain reasons you have only one key from the car, it is advisable to make a duplicate, because when you lose the only key, the car will be difficult to start. In addition, to access the car salon will have to open the castle, and its repair is usually expensive.

The process of manufacturing a duplicate chip key can be divided into two parts. First, its mechanical part is manufactured, which is not difficult, much more difficult to fall with the chip. There are keys that have a chip with a self-copy option. In this case, it will be easy to make a chip key, but for this you need special equipment.

More modern keys models have chips without copying, however, it does not cause problems from professionals, since in this case the chip is created and programmed using professional diagnostic equipment.

How and where can I make a chip key for the car?

Nowadays, the number of proposals for the manufacture of chipped keys and their duplicates increases every day. Who and where only does not offer car owners to make a low-cost chip key. But it is worth considering that after the manufacture of an ordinary mechanical duplicate, your car simply does not start, because the ignition will not respond to signals.

Why only specialized technical centers can solve the problem of making correct chip keys?

Given all the above, it is recommended to apply to only specialized technical centers, where there is a required modern equipment for diagnosis, as well as the manufacture of high-quality chip keys, especially if we are talking about a modern vehicle with a complex electrical system.

Why can problems have problems chip-key?

According to statistics, the largest number of appeals to the technical centers for the manufacture of chipped keys happen in winter. As you know, the car lock is modeled during the night, because of which it becomes not easy to open the car. As a result of cold weather, malfunctions also occur in the functioning of the electronic system, so the ignition and immobilizer sometimes begin to "bug" either break down at all, and when the car owner is trying to open the key to the key, it may fail, in this case, it also needs to urgently make a new chip key.

Tips Profi: What to do if the key is lost?

The loss of the chip key is a fairly common problem. If the key from your car was lost, immediately refer to the manufacture of new with the ability to reprogram (provided that the chip complies with this standard). Manufacturing and reprogramming is performed on specialized equipment, while it is impossible to make the key and reprogram it without the presence of the car.
