To comprehend why a car key needs reprogramming, one should initially understand the relationship in between the key and the lorry's Engine Control Unit (ECU). Since the late 1990s, many manufacturers have actually geared up cars with immobilizer systems.

At the heart of this system is the transponder chip, situated 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 vehicle sends out an electronic burst to the key. The transponder chip reacts by sending out an unique alphanumeric code back to the ECU. If the code matches the series saved in the vehicle's memory, the immobilizer is shut down, and the engine begins. If the codes do not match, the fuel pump and ignition system remain handicapped.
