Transponder Chips

The chip sends out an low-level radio signal once it is activated by an electromagnetic field. The signal is then amplified by the specific antenna that is attached to the ignition barrel of your vehicle. This allows the vehicle's computer system to confirm that the transponder chip in the key is the right one for your specific vehicle.

A circuit within the induction coil will emit an electrical signal when the transponder is inserted into ignition barrel. The signal is taken up by the chip, which then transmits a signal to the vehicle. If the car's computer recognizes this signal as the correct one, it will disable the vehicle immobilizer and allow the engine to start.

The receiver compared this information with the 'allowed' signals in the fob and then either locks or opens the door. If the data doesn't match, a chirping sound is heard and the car isn't allowed to operate.

After the car has been paired with a specific fob, it can only receive signals from the device. In turn, other fobs won't work with the vehicle, even though they appear similar. This ensures the security of the computer system in the car and prevents the use of unauthorized key fobs to gain control over it.
