Transponder Chips Transponder chips can be found in vehicles manufactured in the last 20 years. This is a little piece of plastic on the back of your key that houses an RFID (Radio Frequency Identification) chip with a unique code for the specific vehicle you own. The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. The signal is then amplified by the specific antenna that is positioned around the ignition barrel of your car. The computer system in the vehicle will then confirm that the transponder chip of the key is the right one for your car. This prevents the vehicle from being started by either hot-wiring or by manipulating. The chip inside the key confirms that the owner is the person who is the owner of the vehicle. This can help to reduce car theft. Transponder keys resemble regular metal keys but they have a plastic cap. The chip is inside the plastic portion of these keys. There are a variety of cuts such as a standard cut a Laser cut (also called a sidewinder or Ford Tibbe) and Ford Tibbe. When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil will send out an electrical signal. The signal is received by the chip which sends a signal to the vehicle. If the computer onboard the car detects the signal as being correct it will turn off the car immobilizer to allow the engine start. If the car isn't able to recognize the transponder as being the proper signal, it won't start the engine and alert you with flashing lights and a siren. This system is designed to deter individuals from tampering with the vehicle. However it isn't a foolproof measure of security. A determined and skilled thief can still get around this system by using a specific device that blocks the signal. As you can see there are quite number of advantages to having transponder keys. All car owners should take this into consideration when they want to safeguard their investment and reduce the chance of theft. Key Fobs Key fobs today can do more than just lock and unlock doors. They can also start your vehicle from a distance, make chirping sounds to aid in finding the car, or turn on the heated steering wheel. These extra features could make it difficult to locate your car keys. Key fobs communicate with each with the car via radio frequencies which are transmitted through an antenna that is located in the middle of the key. The communication is encrypted, which helps to keep others from stealing and retransmitting the signal. There are a few different ways to program a key fob, based on the make and model. Certain cars let you 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 additional one. When you press the button on your key fob the microchip inside sends an informational code to the car's receiver that it is paired with. The receiver compares the information with the 'allowed signals' stored on the key fob and then opens or locks the car's door. If the information isn't in line an chirping sound is heard and the car isn't permitted to operate. When a car is connected with a specific fob it will only receive signals from that specific device. Other fobs will not work with the car, even if they look like. This protects the integrity of the computer system of the car and blocks the use of unauthorized key fobs to gain control over it. Most dealerships with newer cars will only accept cars that have original fobs, or genuine replacements supplied by the manufacturer. It is because the only place with the knowledge to create a replacement fob is in the service department of a dealer. Some aftermarket fobs, usually those from older models that have less sophisticated systems can be programmed without the need for a dealer.
