It's a tiny plastic thing on the back of your key that houses an RFID (Radio Frequency Identification) chip with a unique code that is specific to the specific vehicle you own. When activated by an electro-magnetic field the chip emits a low level signal. The signal is taken up by an antenna attached to the ignition barrel. This allows the vehicle's computer system to confirm that the transponder chip that is in the key is the right one for the car you have. This is what prevents doing hot-wiring or altering the ignition system of your vehicle to get it started. The chip inside the key verifies that the owner is the person who owns the vehicle. This will help reduce car theft. Transponder keys resemble regular metal keys, but with a plastic cap. The chip is contained inside the plastic portion of the key, and there are a few different kinds of cuts available on the keys: a cut, a laser cut (also called a sidewinder key) or Ford Tibbe key. A circuit inside the induction coil emits signals when the transponder is placed in the the ignition barrel. The signal is taken up by the chip, which then transmits a signal to the vehicle. If the onboard car computer detects this signal as the correct one, it will shut down the immobilizer on the vehicle and allow the engine to start. If the car does not recognize the transponder signal as being the proper one, it will prevent the engine from starting and will alert you by flashing its lights and sounding a siren. This feature is intended to deter people from trying to alter the vehicle, but it's not a 100% security measure. A skilled and determined thief can still get around this system using a special device that intercepts the signal. As you can see there are quite a number of benefits to having transponder keys. All car owners must take this into consideration when they want to safeguard their investment and decrease the chance of theft. Key Fobs In addition to locking and unlocking doors, starting the car remotely or making chirping sounds to help find a car in a parking space, today's key fobs can also switch on the heated steering wheel or open all windows with a single button push. A lot of these features may seem convenient but they could make it more difficult to keep track of your car keys. Key fobs communicate with each other and the car using radio frequencies which are transmitted by a small antenna located in the center of the key. The signal is encrypted to stop others from intercepting or replicating the signal. There are many ways to program a key fob based on the vehicle's model and make. It is possible to do this yourself, but the majority of newer vehicles require an expert locksmith or dealer to program a replacement or additional fob. When you press the button on a key fob the microchip transmits signals to the receiver in the vehicle with which it is paired. The receiver compared this information to the signals that are allowed inside the fob, and either opens or locks the door. If the data does not match the signals, the car will not be allowed to drive. Once the car has been associated with a particular fob, it can only receive signals from the device. Other fobs will not work with the car, even if they appear similar. This protects the integrity of the computer system of the vehicle and stops the use of unauthorized key fobs to gain control of it. The majority of newer dealerships will only accept vehicles that have original fobs or genuine replacements offered by the manufacturer. This is because the only place with the experience to design a replacement fob is in the service department of a dealer. However, some fobs from the aftermarket typically for older models with less sophisticated systems can be programmed by the consumer without the need of dealers.
