The chip sends out a low-level radio signal when it is activated by an electromagnetic field. The signal is received by a specific antenna attached to the ignition barrel. This allows the computer in your vehicle system to verify that the transponder chip in the key is the right one for your specific vehicle.

The circuit in the induction coil will emit a signal when the transponder is inserted into an ignition barrel. The signal is taken up by the chip, which then transmits a signal the vehicle.

The receiver compared this information to the 'allowed' signals in the fob and then either opens or closes the door. If the data doesn't match the signals, a chirping sound can be heard and the car isn't allowed to function.

After the car has been paired with a specific fob, it will only accept signals from that device. As a result, other fobs won't work with the vehicle even if they look the same. This is to safeguard the integrity of the car's computer system, and also to stop unauthorised key fobs from taking control over the vehicle.

Most dealerships with newer cars will only work with cars with original fobs, or genuine replacements supplied by the manufacturer.
