The key fob communicates with the receiver inside the vehicle by using radio signals. When you press the button on the keyfob, it sends the code to the receiver which then performs the desired function. Key fobs are also very popular with commercial building owners who can incorporate them into a larger access control system. This allows them monitor who enters or leaves and also prevent fobs that were taken or lost.

Like any other electronic device key fobs are susceptible to failure from time to time. As they are constantly jostled around in purses and pockets they are prone to damage or lose their signal.
