How Does an Immobiliser Work?


An immobiliser works by disabling the ignition, the fuel system, and the starter motor. It is activated by a microcircuit that is found in the key that activates a binary code. The code is then relayed to the car's Electronic Control Unit that recognises the correct code, and then it allows the systems to be activated.

An immobilizer refers to an anti theft mechanism which prevents an engine from starting unless an ignition key is present. It works by disabling systems needed to start a car such as the ignition and the fuel supply. The computerized system allows only the right key to operate and start a car.
