More Help can be used for controlling other functions such as 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 signals utilized by cell phones. When the key fob comes within the range of a receiver, it sends a small burst of energy that activates the copper coils that are located on either side of the device. The coils convert the energy from the radio into electricity, powering a microcomputer chip inside the fob. The computer transmits a digitalized version of the unique ID number of your car, which is then verified by the receiver. A lot of newer cars are equipped with remote starter systems that allow you to push a button on the fob to turn on the engine.
