When you press the button on a key fob, the microchip sends signals to the receiver in the vehicle with which it is linked. The receiver compares the information with the 'allowed signals' that are stored in the key fob, and then opens or locks the car door. If the information isn't in line the signals, a chirping sound can be heard and the car isn't permitted to operate.

Once the car has been associated with a particular fob, it can only receive signals from that device. Other fobs will not work with the car, even if they appear identical.
