Transponder Chips If your car was manufactured within the last 20 years, chances are it has a transponder inside of it. It's a small piece of plastic on the back of your key that houses a RFID (Radio Frequency Identification) chip with an individual code for your specific vehicle. The chip sends out a low-level radio signal when it is activated by an electromagnetic field. The signal is then absorbed by the special antenna that is positioned around the ignition barrel of your car. This allows the car's computer system to determine if the transponder chip inside the key is the correct one for your particular car. This prevents the vehicle from starting by hot-wiring or altering the key. The chip in the car key verifies that the owner is the person who is the owner of the vehicle. This will help reduce the possibility of theft from your vehicle. Transponder keys look like regular metal keys but they have a plastic cap. The chip is housed inside the plastic portion of the key and there are a few different cuts that can be found on these keys: a cut laser cut (also called a sidewinder key) or Ford Tibbe key. When the transponder key is placed in the ignition barrel, a circuit within of the induction coil will send out the signal. The signal is taken up by the chip, which then transmits a signal to the vehicle. If the computer onboard the car recognizes the signal as correct it will turn off the vehicle immobilizer so that the engine can start. If the car does not recognize the transponder signal as being the correct 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, however it isn't a foolproof security measure. A skilled and skilled criminal can still get around this system using a special device that detects the signal. As you can see, there are quite a number of advantages to having transponder keys. Every car owner should consider this if they wish to protect their investment and reduce the risk of theft. Key Fobs In addition to locking and unlocking doors, launching the car remotely or making sound chirps to help locate a car in a parking lot keys of today can also turn on a heated steering wheel, or roll down all windows with just a single press. A lot of these additional features may appear convenient but they could make it difficult for you to keep the keys to your car. Key fobs are able to communicate with each other and with the car through radio frequencies that are transmitted via a small antenna located in the middle of the key. This communication is encrypted to prevent others from stealing or modifying the signal. There are a few different ways to program a key fob depending on your vehicle's model and make. It is possible to do this yourself, but the majority of newer automobiles require a dealer or professional locksmith to program a replacement or additional fob. When you press the button on a key fob the microchip transmits a signal 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 closes the door. If the information does not match, the car will not be allowed to run. Once the car is paired with a specific fob, it will only accept signals from that device. This means that other fobs will not work with the vehicle, even though they look the same. This protects the integrity of the computer system of the car and blocks the use of unauthorized key fobs to gain control of it. Most dealerships with newer cars will only deal with cars that have original fobs, or genuine replacements supplied by the manufacturer. It is because the only place that has the expertise to prepare a replacement fob is in a dealer's service department. However, some aftermarket fobs that are typically designed for older models with less sophisticated systems can be programmed by the consumer without the need of dealers.
