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

Once the car has been connected to a specific fob, it can only receive signals from that device. Other fobs will not work with the car, even if they appear similar. This ensures the security of the computer system that runs the vehicle and stops the use of unauthorized key fobs to gain control of it.
