When the key is placed into the ignition or the "Start" button is pushed, the Cheap Car Key Programming's Engine Control Unit (ECU) sends out an electronic signal to the key. If the digital signature of the Key Reprogramming Service matches what is saved in the ECU, the engine begins. If not, the immobilizer kills the fuel flow, avoiding theft. Mobile key programming is the act of teaching the ECU to acknowledge a new digital signature.
