When the key is placed 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 flow, avoiding theft. Mobile key programming is the act of teaching the ECU to acknowledge a new digital signature.
