An immobiliser system is an electronic security feature that prevents thieves from starting your vehicle.

If the codes don't match, your engine will immediately shut down to prevent theft.

The ECU examines the code against the one it has stored in its memory and activates both the fuel system as well as the ignition circuit if they are compatible. If the codes don't match, your engine won't be able to start - even if a burglar tries to short-circuit the ignition circuit.
