Transponder Chips Transponder chips can be found in vehicles manufactured within the past 20 years. It's a tiny plastic thing inside the head of your key which contains a RFID (Radio Frequency Identification) chip with a unique code that is specific to your specific vehicle. The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. The signal is then received by a specific antenna attached to the ignition barrel. The computer system in the vehicle will then confirm that the key's transponder chip is the correct one for your vehicle. This prevents the vehicle from being started by hot-wiring or altering the key. The chip inside the key ensures that the owner is the one who owns the vehicle. This helps to reduce the risk of theft from your car. Regular transponder keys are designed like regular metal keys with an outer layer of plastic. The chip itself is housed within the plastic part of the key, and there are different kinds of cuts available on these keys: a cut, a laser cut (also called a sidewinder) or Ford Tibbe key. The circuit in the induction coil will emit signals when the transponder is inserted into ignition barrel. The signal will then get taken up by the chip and cause it to send a signal back to the car. If the onboard car computer detects this signal as the right one, it will turn off the vehicle's immobilizer and allow the engine to begin. If the vehicle does not recognize the transponder signal as being the proper one, it will keep the engine from running and will alert you by flashing its lights and sounding siren. This function is designed to discourage those who would attempt to alter the vehicle. However it isn't an absolute security measure. A skilled and skilled criminal could still bypass this system with a specially designed device that detects the signal. It is evident that the transponder is a good option. This is something that all vehicle owners should consider if want to protect their investment and decrease the chance of theft. Key Fobs In addition to locking and unlocking doors, starting the car remotely or making sound chirps to help locate the car in a parking space Key fobs today can also switch on the heated steering wheel or roll down all of the windows with a single click. These extra features could make it difficult to find your car keys. Key fobs communicate with one with the car via radio frequencies that are transmitted through a small antenna located in the middle of the key. The communication is encrypted, which helps stop others from stealing and retransmitting the signal. You can program a key fob in a variety of ways depending on the model and brand of your car. Certain models allow you to do it yourself. However, most newer models require you to visit a professional locksmith or dealer to program a replacement key fob or additional one. When you press a key fob's button the microchip inside sends an encoded code to the car's radio that it is linked to. The receiver compared the information with the 'allowed signals' stored in the key fob, and then it opens or closes the car's door. If the information doesn't match the signals, a chirping sound can be heard and the car isn't able to operate. When a car is connected with a particular fob, it will only accept signals from the device that is associated with it. As a result, other fobs will not work with the vehicle, even though they look the same. This protects the integrity of the vehicle's computer system, and also to stop unauthorised key fobs from taking control over the vehicle. Most newer car dealerships will only work with cars with original fobs or genuine replacements offered by the manufacturer. This is because preparing an appropriate replacement fob requires technical and security expertise which can only be obtained in the dealer service department. Some fobs from the aftermarket, especially those from older models with less advanced systems can be programmed with out the need for a dealer.
