Transponder Chips If your car was built in the past 20 years, it is likely that it has a transponder inside of it. This is a little piece of plastic in the head of your key that contains an RFID (Radio Frequency Identification) chip with a unique code for your particular vehicle. When it is activated by an electro-magnetic field, the chip emits a low level signal. The signal is then taken up by an antenna that is attached to the ignition barrel. This allows the vehicle's computer system to determine if the transponder chip inside the key is the correct one for the car you have. This prevents the vehicle from being started through hot-wiring or manipulating. The chip in the key also confirms that you are the legitimate owner of the vehicle.

The chip itself is housed in the plastic portion of the key and there are a few different kinds of cuts available on these keys: a cut, a laser cut (also known as a sidewinder key) or Ford Tibbe key. A circuit within the induction coil emits an electrical signal when the transponder is placed in the an ignition barrel. The signal is absorbed by the chip, which then transmits a signal the vehicle. If the onboard car computer detects this signal as the correct one, it will disable the vehicle immobilizer and allow the engine to start. If the vehicle does not recognize the transponder signal as the proper one, it will prevent the engine from starting and will notify you by flashing its lights and sounding an alarm. This is designed to discourage people from trying to alter the vehicle, but it isn't a foolproof security measure.

Many of these extra features may seem convenient however they could make it harder for you to keep track of your car keys. Key fobs make use of radio frequencies to communicate with one another and with the car. The frequencies are transmitted through a small antenna located within the middle of the key. The signal is encrypted to block other key fobs from stealing or modifying the signal. There are several ways to program a key fob, based on the vehicle's model and make. Certain models allow you to do this by yourself. However, the majority of modern models require you to visit an expert locksmith or dealer to program a new key fob, or an alternative one. When you press the button on your key fob the microchip inside sends an encoded code to the car's radio that it is paired with. The receiver then compares this information to the 'allowed' signals stored inside the fob, and either locks or opens the door. If the information does not match, the car will not be allowed to operate. When a car is connected with a particular fob, it will only accept signals from that specific device. In turn, other fobs won't work with the vehicle even though they appear similar. This helps to protect the integrity of the car's computer system and to prevent the use of unauthorized key fobs to gain control of the vehicle. The majority of car dealers who are newer will only work on a car with original fobs or genuine replacements that are offered by the manufacturer. This is because preparing an appropriate replacement fob requires technical and security skills which can only be obtained in the dealer's service department. However, some fobs from the aftermarket — usually those for older models that have less sophisticated systems — can be programmed by customers without the need for a dealership.
