The key fob uses radio signals to communicate with a receiver that is installed in the vehicle. When you press the key fob, it transmits an encoded code to the receiver, which in turn responds by performing the function you want. Commercial building owners also use key fobs as they allow them to connect them to an entire system of access control. This allows them monitor who enters or leaves and also stop fobs that have been lost or stolen.

Modern keyless entry systems utilize rolling code technology to safeguard against hacking and other security breaches. It is important to keep in mind that even this technology is not 100% secure. Utilizing a technique known as "replay attack," a thief can use the transmitter of the key fob to transmit a message which is recorded by the vehicle's receiver.

The most commonly used method to program new car keys is to place the key fob in the ignition and turning it several times in a specific sequence. This puts the car in a "programming mode," and once it is in this mode, one or more fob buttons are pressed to transmit the digital identity code to the car's computer. The computer then saves the code and removes the car from programming mode.
Certain manufacturers require you to use a specific advanced programmer to program key fobs. They are costly and are difficult to use for the average person. It is recommended to delegate the work to an automotive locksmith or dealer.
