Immobiliser Systems

An immobiliser is an electronic security measure that stops thieves from starting your car. It works by sending an electronic signal from the car to the key whenever you attempt to start it. The electronic chip in the key responds by transmitting a unique code that must match the one of the vehicle in order for it to start. If the codes do not match, the engine will shut off immediately to stop theft.

Modern smart keys and fobs have an embedded transponder that stores electronic security information in a format that can't be copied easily. When your key or fob is inserted into the ignition, it transmits the code to a device within the ECU. The ECU then compares it with the code stored in its memory. It then activates the ignition system and fuel circuit if the two match. If the codes don't match, your engine won't start - even if a burglar tries to short-circuit the ignition circuit.
