Transponder Keys Transponder keys, also known as chip keys, are comprised of an embedded microchip that is embedded in the head of plastic.

The car won't start unless this response is received. This is a relatively recent technology for preventing theft, but it has proven effective in deterring theft. Transponder chips can be found in most modern cars.

Key Fobs Since their introduction in the year 1990, key fobs are now an integral part of cars. These tiny devices are much more than a way to unlock doors and start the vehicle.

When a button is pressed on the key fob, it transmits a signal that contains a unique code to a receiver close to the locking system of the vehicle. The receiver interprets the code and then performs the desired action, such as unlocking the doors or launching the engine. Some key fobs can also be used to control other functions, for example, activating the car's panic alarm system, or disarming and arming the security system. The radio frequency (RF) signals utilized by key fobs are akin to the signals that are used by cell phones. When the key fob is within range of a receiver it sends a small burst that energizes the copper coils on either side of the device. These coils convert energy from the radio into electricity, which powers a microcomputer embedded in the fob. The computer then transmits a digitized version of your car's unique ID number, which is verified by the receiver. Many of the latest vehicles are equipped with remote starter systems that allow the user to push a button on the fob to turn on the engine.
