Electronic immobilizer

The engine immobilizer is an essential safety feature that helps to protect against theft of cars by ensuring that only the correct key is used to start the vehicle.

This system has been in operation for over 20 years and has helped in reducing vehicle theft. It's also a good way to prevent hotwiring, which is the practice of bypassing the ignition switch by connecting wires between the ignition coil and the fuel pump relay.

The chip transmits a passcode from the key fob or key to the immobilizer system of the vehicle, which is integrated into the PCM (or BCM), instrument cluster and smart junction boxes or other modules. The immobilizer device then validates the passcode and allows the engine to start if the passcode is right.
