Transponder Chips If your car was built in the last 20 years, chances are it has a transponder chip inside of it. It's a tiny plastic piece in the head of your key that houses an RFID (Radio Frequency Identification) chip with a unique code that is specific to your particular vehicle. When it is activated by an electro-magnetic field, the chip emits a low-level signal. The signal is then absorbed by a special antenna that is attached to the barrel of ignition. The computer system of the vehicle is then able to verify that the key's transponder chip is the correct one for your car. This is what prevents doing hot-wiring or altering the ignition system of your vehicle to start it. The chip inside the key verifies that the owner is the one who owns the vehicle. This can reduce car theft. Transponder keys resemble regular keys made of metal but they have caps made of plastic. The chip is inside the plastic portion of these keys. There are several different cuts such as a standard cut laser cut (also known as a sidewinder or Ford Tibbe) and a Ford Tibbe. A circuit inside the induction coil will emit a signal when the transponder is put into the ignition barrel. The signal will be taken up by the chip, causing it to transmit a signal to the car. If the computer in the car recognizes the signal as correct it will turn off the vehicle immobilizer so that the engine can start. If the car doesn't recognize the transponder as being the proper signal, it won't start the engine and alert you with flashing lights and a siren. This is designed to discourage people from trying to alter the vehicle, however it's not a 100% security measure. A skilled and determined thief could still evade this system using a special device that blocks the signal. As you can see there are quite few advantages to getting a transponder key. This is something that all car owners should consider if want to protect their investment and minimize the chance of theft. Key Fobs Key fobs today offer more than locking and unlock doors. They can also start the car remotely, make chirping noises to aid in finding the car, or switch on the heated steering wheel. These additional features could make it difficult to find your car keys. Key fobs communicate with each with the car via radio frequencies that are transmitted by a small antenna located in the middle of the key. The communication is encrypted, which helps keep others from stealing and re-transmitting the signal. There are a few different ways to program a key fob based on the model and make. It is possible to do this yourself, but most newer cars require that you visit an expert locksmith or dealer to program a replacement or an additional fob. When you press the button on a key fob, the microchip transmits a signal to the receiver in the vehicle that it is paired. The receiver compared the information with the permitted signals stored in the key fob and then it opens or closes the car's doors. If the information does not match, the car will not be allowed to run. Once the car is linked with a specific fob, it will only receive signals from that device. Other fobs will not work with the car, despite the fact that they appear similar. This is to safeguard the integrity of the vehicle's computer system and to prevent unauthorized key fobs from gaining control of the vehicle. The majority of newer dealerships will only work with cars with original fobs, or genuine replacements supplied by the manufacturer. The reason for this is that the only place with the expertise to prepare a replacement fob is in the service department of a dealer. Some fobs from the aftermarket, especially those for older models that have less sophisticated systems can be programmed with out the need for a dealership.
