Transponder Chips Transponder chips are likely be found in cars that were manufactured within the past 20 years. It's the tiny piece of plastic in the head of your car key that houses an RFID (Radio Frequency ID) chip that has a unique code to your vehicle. The chip sends out an low-level radio signal once it is activated by an electromagnetic field. This signal is then received by a specific antenna that is attached to the ignition barrel. The computer system in the vehicle can then verify that the chip in the key's transponder is the right one for your vehicle. This stops the vehicle from being started through hot-wiring, or by manipulating. The chip inside the key confirms that the owner is the one who owns the vehicle. This can reduce car theft. Transponder keys appear like regular metal keys but they have a plastic cap. The chip is contained inside the plastic portion of the key and there are a few different cuts that can be found on the keys: a standard cut, a laser cut (also called a sidewinder key), or a Ford Tibbe key. The circuit in the induction coil emits a signal when the transponder is inserted into ignition barrel. The signal is received by the chip which then transmits a signal to the vehicle. If the onboard car computer recognizes this signal as the right one, it will turn off the immobilizer on the vehicle and allow the engine to start. If the car doesn't recognize the transponder as a valid signal, it will not start the engine, and will notify you via flashing lights and an alarm. This system is designed to deter people from tampering with the vehicle. However it's not an absolute security measure. A skilled and determined criminal could still be able to bypass this system by using a special device to detect the signal. You can see that the transponder is an excellent option. Every car owner should take this into consideration when they want to safeguard their investment and minimize theft risk. Key Fobs Key fobs today do more than just lock and unlock doors. They can also start the car remotely, emit chirping sounds to aid in finding a car, or turn on the heated steering wheel. A lot of these features might seem useful but they could make it difficult for you to keep the keys to your car. Key fobs communicate with one other and with the car through radio frequencies that are transmitted by an antenna in the middle of the key. This communication is encrypted, which helps prevent others from intercepting and re-transmitting the signal. Keyfobs can be programmed in a variety of ways depending on the model and brand of your car. Certain cars let you do this yourself. However, most newer models require you to visit an expert locksmith or dealer for them program a replacement key fob or an additional one. When you press the button on a key fob, the microchip sends signals to the receiver in the vehicle with which it is linked. The receiver compares the information with the 'allowed signals' that are stored in the key fob and then opens or locks the car's doors. If the data doesn't match the signals, a chirping sound can be heard and the car isn't permitted to operate. Once the car has been associated with a particular fob, it can only receive signals from the device. As a result, other fobs won't be able to work with the vehicle, even though they appear similar. This ensures the security of the computer system that runs the car and blocks unauthorised key fobs from taking control over it. The majority of newer dealerships will only work with cars with original fobs, or genuine replacements offered by the manufacturer. This is because preparing the replacement fob is a process that requires technological and security knowledge that is only available in the dealer's service department. However, some fobs from the aftermarket -- usually those for older models that have less sophisticated systems -- can be programmed by consumers without the need of dealers.
