The receiver compares this information to the 'allowed' signals inside the fob, and either opens or closes the door. If the data doesn't match the signals, a chirping sound can be heard and the car isn't allowed to operate.

Once the car is paired with a specific fob it will only receive signals from that device. Other fobs won't work with the car, despite the fact that they appear identical. This protects the integrity of the computer system that runs the vehicle and stops unauthorized key fobs gaining control of it.
