When activated by an electro-magnetic field, the chip emits a low-level signal. The signal is then taken up by an antenna that is attached to the barrel of ignition. The computer system of the vehicle will then confirm that the transponder chip of the key is the right one for your car.

If the information isn't in line 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 safeguards the integrity of the computer system that runs the car and blocks unauthorised key fobs from taking control over it.
