Some key fobs are capable of performing other functions like activating a panic alarm or disarming or rearming the security system.
The radio frequency (RF) signals used by key fobs are the same as the ones used by cell phones. When the key fob is in the range of a receiver it transmits a small burst of energy, which then energizes copper coils on both sides of the device. These coils convert energy from the radio into electricity, supplying power to a microcomputer embedded in the fob. The computer transmits a digitalized version of the unique ID number of your car, which is later verified by the receiver.
