When the key is placed into the ignition or the "Start" button is pushed, the lorry sends out an electronic burst to the key. The transponder chip reacts by sending an unique alphanumeric code back to the ECU. If the code matches the sequence stored in the vehicle's memory, the immobilizer is shut down, and the engine begins. If the codes do not match, the fuel pump and ignition system stay handicapped.
