Transponder Chips

The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. This signal then gets taken up by the antenna that is fitted around the ignition barrel of your car. The computer system of the vehicle will then confirm that the transponder chip of the key is the correct one for your car.

If the onboard car computer recognizes this signal as the correct one, it will disable the vehicle's immobilizer and allow the engine to start.

If the information does not match the signals, the car will not be allowed to drive.
After the car has been paired with a specific fob, it will only accept signals from that device. Other fobs will not work with the car, despite the fact that they look identical.
