The chip sends out a low-level radio signal when it is activated by an electromagnetic field. This signal is then taken up by an antenna attached to the ignition barrel. This allows the car's computer system to verify that the transponder chip that is in the key is the correct one for your particular car.

The circuit in the induction coil emits signals when the transponder is inserted into the ignition barrel. The signal is absorbed by the chip, which then transmits a signal to the vehicle. If the computer inside the car recognizes the signal as correct it will turn off the car immobilizer so that the engine can start.

If the vehicle does not recognize the transponder signal as the proper one, it will stop the engine from running and will alert you by flashing its lights and sounding siren. This feature is intended to discourage people from trying to alter the vehicle, but it's not a 100% security measure.

The receiver compared the information with the 'allowed signals' that are stored in the key fob, and then opens or locks the car's door. If the information isn't in line, a chirping sound is heard and the car isn't able to function.

After the car has been paired with a specific fob, it only accepts signals from that device. This means that other fobs won't work with the vehicle even if they look the same. This protects the integrity of the computer system that runs the car and blocks the use of unauthorized key fobs to gain control over it.

Most dealerships with newer cars will only deal with cars with original fobs or genuine replacements offered by the manufacturer.
