When you press the button on the keyfob it transmits the code to the receiver which then performs the desired function. Commercial building owners also make use of key fobs to connect them to an entire system of access control. This allows them to keep track of who enters and exits and prevent fobs from being stolen or lost.

Based on the make and model of your car, you might be capable of programming new keys on your own or you may have to employ an automotive locksmith to complete the task. Some car manufacturers have an onboard program that is specifically designed for their vehicles, while others require you have an advanced programmer attached to the OBD2 connector.
The most common method of programming new keys for cars is to insert the key fob in the ignition and engage it in a particular sequence. This puts the car in the "programming mode," and once it is in this mode, one or more fob buttons are pressed to send the digital identity code to the car's computer. The computer then saves this code and takes the car out of programming mode.
