Transponder Chips Transponder chips can be found in vehicles manufactured in the last 20 years. It's a tiny plastic thing in the head of your key that contains an RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle. The chip emits a low-level radio signal when it is activated by an electromagnetic field. The signal is received by a specific antenna that is attached to the ignition barrel. The computer system in the vehicle will then confirm that the chip in the key's transponder is the right one for your car. This prevents the vehicle from being started by hot-wiring, or by tampering. The chip inside the key also proves that you are the genuine owner of the vehicle. This can help to reduce car theft. Regular transponder keys are designed like regular keys, but with an outer layer of plastic. The chip is housed inside the plastic portion of the key, and there are a few different kinds of cuts available on the keys: a standard cut laser cut (also called a sidewinder key), or a Ford Tibbe key. A circuit within the induction coil emits an electrical signal when the transponder is inserted into ignition barrel. The signal is received by the chip which then transmits a signal the vehicle. If the computer on the car recognizes this signal as the right one, it will shut down the vehicle immobilizer and allow the engine to begin. If the vehicle doesn't recognize the transponder as being the proper signal, it will not start the engine, and will warn you with flashing lights and a siren. This system is designed to deter those who would attempt to alter the vehicle. However it's not an unbreakable security measure. A determined and skilled thief could still bypass this system using a special device that intercepts the signal. As you can see there are quite number of benefits to having transponder keys. Every car owner should take this into consideration when they want to safeguard their investment and minimize the chance of theft. Key Fobs Key fobs today do more than just lock and unlock doors. They can also turn on the car remotely, make chirping noises to aid in finding the car, or switch on the heated steering wheel. These extra features can make it difficult for you to locate your car keys. Key fobs utilize radio frequencies to communicate with one another and with the car. These frequencies are transmitted by a small antenna inside the middle of the key. The communication is encrypted, which helps to prevent others from intercepting and retransmitting the signal. You can program a keyfob in a variety of ways depending on the model and brand of your car. Some cars allow you to do this yourself. However, the majority of modern models require you to visit a professional locksmith or dealer in order to program a new key fob or additional one. When you press the button on a key fob, the microchip sends a signal to the receiver in the car with which it is linked. The receiver compared this information with the 'allowed' signals stored in the fob and then either opens or closes the door. If the information doesn't match an chirping sound is heard and the car isn't permitted to operate. Once the car has been connected to a specific fob, it can only receive signals from that device. As a result, other fobs will not work with the vehicle even if they look the same. This protects the integrity of the computer system of the vehicle and stops unauthorized key fobs gaining control of it. The majority of car dealers who are newer will only work on cars with original fobs or genuine replacements that are supplied by the manufacturer. This is due to the fact that preparing a replacement fob requires technological and security knowledge that can only be found in the dealer service department. However, some aftermarket fobs typically for older models that have less sophisticated systems can be programmed by customers without the need for an authorized dealer.
