What is a Transponder Key?
The term "transponder" is a portmanteau of "transmitter" and "responder." At its core, a transponder key is a standard ignition key with a built-in microchip situated inside the plastic head of the key. This chip does not require a battery; instead, it is powered by the radio frequency (RF) energy sent out by the lorry's ignition cylinder.

When a chauffeur inserts the key into the ignition and turns it, the automobile's Engine Control Unit (ECU) sends an electronic message to the key. The transponder chip receives this message and responds with a special alphanumeric code. If the code matches the one stored in the car's computer, the immobilizer is deactivated, and the engine begins. If the codes do not match, or if a non-transponder key is utilized, the fuel pump will remain disabled, and the engine will not crank.
