If the code on the car's computer matches the signal from the key, it will deactivate the immobiliser and allow the engine to begin.
The key that has a transponder can also be referred to as a "fob" or a "smart" key, as it is more difficult to duplicate than a mechanical key. With the help of special techniques, it is feasible to copy a conventional car key but not a transponder key. Transponder chips are powered by an infrared signal, not battery power.
To activate the transponder, the ignition cylinder has to be in the ON position. The ring emits a blast of IR energy which is absorbed by the microchip within the key. mouse click the up coming document responds by sending a unique code your car's immobiliser.
