At the heart of this system is the transponder chip, located inside the head of the key or the body of the key fob. When the key is inserted into the ignition or the "Start" button is pushed, the automobile sends out an electronic burst to the key. The transponder chip responds by sending out a distinct alphanumeric code back to the ECU. If the code matches the series kept in the lorry's memory, the immobilizer is shut down, and the engine begins. If the codes do not match, the fuel pump and ignition system remain handicapped.
