The receiver compares the information with the 'allowed signals' stored on the key fob and then locks or opens the car's doors. If the data doesn't match, a chirping sound is heard and the car isn't allowed to operate.

Once the car is paired with a specific fob, it will only accept signals from that specific device. As a result, other fobs won't work with the vehicle even if they appear similar. This ensures the security of the computer system that runs the vehicle and stops unauthorized key fobs gaining control over it.

Most dealerships with newer cars will only work with cars with original fobs, or genuine replacements sold by the manufacturer. This is because preparing a replacement fob requires technological and security knowledge which can only be obtained in the dealer service department. Some fobs from the aftermarket, especially those for older models with less sophisticated systems can be programmed with out the need for a dealership.
