What is the immobilizer crawler for?

Under the expression "immobilizer bypass" means a number of technologies, the use of which allows you to start the car using the key. All of these technologies are combined under one word "bypass".

The installation of regular immobilizers on a car abroad was stimulated by certain restrictions when applying for insurance, in our country there was no such incentive and still is not. Now, most foreign cars in the country are equipped with a system called "regular immobilizer". The meaning of this system is that you can start the car with only one ("native") key, the code of which is registered in the car's security system. This was done in order to prevent the hijacker from starting the car with a master key or by shorting the wires. But in some situations, an immobilizer crawler is needed.

When installing the immobilizer, a number of the following problems may occur. The first is the occurrence of a number of unpleasant difficulties when the key is lost or the device itself fails. The second is that, according to the statistics of car theft, he does not give any guarantees. The third is the incompatibility of the immobilizer system withautorun.

So I had to come up with an immobilizer crawler so that, if desired, I would not depend on it.

In order to apply this or that immobilizer “bypass” technique, you first need to know how it works. Regardless of the presence or absence of control buttons on the key, all without exception have a small chip called a transfer. It continuously emits a low power RF signal. In the ignition lock there is an immobilizer antenna that reads this signal, which recognizes exactly “its” key, or rather the chip located on the “native” key.

Today, alarms with auto start have become very popular among owners of expensive foreign cars. But what if you want to combine both autostart and immobilizer?

Of course, you can't leave the key in the ignition, but there is a way out. To implement remote engine start of a car with an immobilizer, the above device called "immobilizer crawler" is used. For its operation, it is necessary to install a chip from the spare car key or the entire spare key into it. Sometimes it is more convenient to make a duplicate chip, the production cost of which will cost an average of one hundred dollars, or order another key from an authorized dealer of the brand of car you drive.

The immobilizer crawler is installed in the back of the car, in a certain way connecting it both to the alarm with auto start and to the device itself. Information is read from the chip only with permissionsignaling and only at the moment of starting the engine. Thus, the functions of the immobilizer are not violated, and it is still impossible to start the car by any improvised means. But the operation of the alarm with auto start is preserved, that is, the possibility of remote engine start is not violated. This greatly simplifies operation.
