The receiver compared the information with the 'allowed signals' stored on the key fob and then it opens or closes the car's door. If the information doesn't match the signals, the car will not be allowed to drive.

Once the car has been paired with a specific fob, it can only receive signals from that device. Other fobs won't work with the car, despite the fact that they appear similar.
