An immobiliser or immobilizer is an electronic security device fitted to an automobile that prevents the engine from running unless the correct transponder car key (or other token) is present. This prevents the car from being “hot wired” after entry has been achieved and thus reduces motor vehicle theft.

What is Engine Immobiliser?

An Immobiliser or the Engine Immobiliser is an electronic security device which the modern cars use. The Engine Immobiliser uses an electronic chip embedded into the ECU of the vehicle.

How Engine Immobiliser Works:

The engine immobilizer is an anti-theft system built in the engine ECU. It prevents the engine from starting without using vehicle’s authorized key. This system uses a special digitally coded key or a Smart Key fob. This key contains a transponder chip. It stores the electronic security code or simply the vehicle’s password. The ECU does NOT activate the fuel system and the ignition circuit if the code in the key & that stored in the immobilizer does not match.
