What is a Transponder and how does it work?
A transponder is a part of the key which disarms the immobiliser when it is used to start the engine of a vehicle. They have mostly become an industry standard in all modern cars manufactured after 1997.
When you place your key into the ignition barrel and turn it to start your vehicle, the barrel emits a magnetic field which in-turn sends a small amount of power to the microchip/RFID chip located in the head of the key.
With this small charge, the transponder chip is able to communicate with the Engine Control Unit/Immobiliser Unit contained within the vehicle itself. If the codes from the transponder chip matches that of the immobiliser unit, the vehicle will start. However, if the codes do not match, or the vehicle is attempted to be started with a standard key, the engine will not start.
What is the difference between genuine and aftermarket car keys?
The main difference between genuine car keys and the aftermarket alternative is price. Genuine keys are more expensive, however our aftermarket variations are much more durable and even utilise identical RFID transponder chip as the genuine model.
