When a driver tries to start the vehicle, the Engine Control Unit (ECU) sends an electronic signal to the key. The chip in the key receives this signal and responds with an unique digital code. If the code matches what is saved in the ECU's memory, the immobilizer is shut off, and the engine begins.

The Professional Reprogramming Process
