Key fobs communicate with one with the car via radio frequencies which are transmitted by a small antenna located in the middle of the key. This communication is encrypted to block other key fobs from stealing or modifying the signal. Keyfobs can be programmed in different ways based on the make and model of your vehicle. Certain cars let you do this yourself. However, most newer models require you to visit an expert locksmith or dealer in order to program a new key fob, or an alternative one. When you press the button on a key fob, the microchip transmits signals to the receiver inside the car that it is paired. The receiver compares this information to the signals that are allowed in the fob and then either locks or opens the door. If the information doesn't match the signals, the car will not be allowed to operate. After the car has been connected to a specific fob, it can only receive signals from that device.

This protects the integrity of the computer system of the vehicle and stops the use of unauthorized key fobs to gain control over it. Most newer car dealers will only work on cars with original fobs or genuine replacements supplied by the manufacturer.

Certain aftermarket fobs, typically those from older models that have less advanced systems, can be programmed without the need for a dealer.
