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 pressed, the lorry sends out an electronic burst to the key. The transponder chip reacts by sending a special alphanumeric code back to the ECU. If the code matches the series stored in the vehicle's memory, the immobilizer is shut down, and the engine starts. If the codes do not match, the fuel pump and ignition system remain disabled.
