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 an integrated microchip located inside the plastic head of the key. This chip does not need a battery; instead, it is powered by the radio frequency (RF) energy sent out by the automobile's ignition cylinder.

When a driver inserts the key into the ignition and turns it, the vehicle's Engine Control Unit (ECU) sends out an electronic message to the key. The transponder chip receives this message and responds with a distinct alphanumeric code. If the code matches the one saved in the lorry's computer system, the immobilizer is disarmed, and the engine begins. If the codes do not match, or if a non-transponder key is utilized, the fuel pump will remain handicapped, and the engine will not crank.
