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 located 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 by the car's ignition cylinder.

When a chauffeur inserts the key into the ignition and turns it, the vehicle's Engine Control Unit (ECU) sends an electronic message to the key. The transponder chip receives this message and reacts with an unique alphanumeric code. If the code matches the one stored in the automobile'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 handicapped, and the engine will not crank.
