When it is activated by an electromagnetic field, the chip emits a low-level signal. This signal is then taken up by an antenna that is attached to the ignition barrel. This allows the car's computer system to determine if the transponder chip in the key is the correct one for the car you have.

The receiver then compares the data with the permitted signals stored in the key fob and then locks or opens the car's doors. If the data doesn't match an chirping sound is heard and the car isn't able to operate.

Once the car is linked with a specific fob, it will only receive signals from that specific device.
