vehicle immobiliser

A vehicle immobiliser is an anti-theft electronic security device that is fitted into a motor vehicle which prevents the engine from running until the correct key is inserted into it. It basically consists of two parts, a transponder in the ignition key and the receiver in the car itself. It basically works in this way that if someone starts the engine then the vehicle sends a request to the key. If the key sends back a pre-defined signal to the engine then the immobiliser sends a command to the engine control unit to start.

In this way, they can prove to be a great security device against offenders who use mechanical techniques for hijacking a vehicle.
