This technology makes use of a transponder chip-equipped fob key. The engine control unit does not turn on the fuel system or the ignition when the security code stored in the chip is incorrect, which prevents the car from starting.

The engine management system receives signals when the user inserts the key. The engine starts if the proper key is turned and the code matches. Immobilizers with rolling or changing codes have been developed recently, making the system even more secure.
