A circuit inside the induction coil will emit a signal when the transponder is inserted into the ignition barrel. The signal is taken up by the chip, which then transmits a signal to the vehicle. If the computer inside the car is able to recognize the signal as valid it will turn off the car immobilizer so that the engine can start.

The receiver compared this information to the 'allowed' signals inside the fob, and either opens or closes the door. If the information doesn't match, a chirping sound is heard and the car isn't able to operate.
Once the car is paired with a particular fob, it will only receive signals from that device. Other fobs won't work with the car, despite the fact that they appear like.
