When your key or fob is put into the ignition, it transmits the code to a device within the ECU. The ECU examines the code against the one stored in its memory, and it activates both the fuel system and the ignition circuit if they are compatible. If the codes do not match and the engine does not start, even in the event that the ignition circuit is damaged by a thief.
