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

When a driver inserts the key into the ignition and turns it, the lorry's Engine Control Unit (ECU) sends out 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 disarmed, and the engine starts. If the codes do not match, or if a non-transponder key is used, the fuel pump will stay handicapped, and the engine will not crank.
