Because the late 1990s, the majority of lorries have been equipped with a transponder chip hidden inside the plastic head of the key. When the key is inserted into the ignition or the "Start" button is pushed, the car's Engine Control Unit (ECU) sends an electronic signal to the key. If the digital signature of the key matches what is stored in the ECU, the engine starts. If not, the immobilizer eliminates the fuel circulation, preventing theft. Mobile key programming is the act of teaching the ECU to recognize a new digital signature.
