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

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