Modern vehicle security counts on a system typically referred to as a transponder system. "Transponder" is a portmanteau of "transmitter" and "responder." Inside the plastic head of a Car Key Reprogramming UK key or within a keyless entry fob is a small microchip.

When a motorist tries to start the automobile, the Engine Control Unit (ECU) sends an electronic signal to the key. The chip in the key receives this signal and responds with a special digital code. If the code matches what is kept in the ECU's memory, the immobilizer is shut off, and the engine begins. If the codes do not match-- or if the chip is missing out on-- the car will stay stable, even if the physical blade of the key turns the ignition.

4. Malfunctioning Transponder
Like any electronic component, a transponder chip can fail due to physical shock, water damage, or internal circuitry decay. When this takes place, the car will fail to acknowledge the key, requiring a replacement and a new programming session.
The Professional Reprogramming Process
