Transponder Chips If your car was manufactured in the past 20 years, chances are it contains a transponder chip within of it. It's a tiny plastic thing on the back of your key that houses an RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own. When it is activated by an electro-magnetic field, the chip emits a low level signal. The signal is then taken up by an antenna attached to the ignition barrel. The computer system of the vehicle can then verify that the transponder chip of the key is the correct one for your vehicle. This is what stops doing hot-wiring or altering the vehicle's ignition system to start it. The chip in the car key confirms that the owner is the person who owns the vehicle. This can reduce car theft. Regular transponder keys are designed like regular keys and have an outer layer of plastic. The chip is contained in the plastic portion of the key and there are a few different cuts that can be found on the keys: a standard cut laser cut (also called a sidewinder), or a Ford Tibbe key. A circuit inside the induction coil will emit an electrical signal when the transponder is put into the ignition barrel. The signal is absorbed by the chip, which sends a signal to the vehicle. If the computer in the car detects the signal as valid, it will disable vehicle immobilizer, allowing the engine to start. If the car does not recognize the transponder signal as being the proper one, it will stop the engine from running and will alert you by flashing its lights and sounding an alarm. This feature is designed to discourage people from tampering with the vehicle. However, it is not an unbreakable security measure. A skilled and determined thief could still evade this system using a special device that intercepts the signal. It is evident that the transponder is a good option. This is something that all vehicle owners should consider if 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 remotely, make chirping noises to aid in finding the car or switch on the heated steering wheel. These extra features could make it difficult to locate your car keys. Key fobs use radio frequencies to connect with one another and with the car. These frequencies are sent by a small antenna inside the middle of the key. The signal is encrypted to block other key fobs from stealing or modifying the signal. There are many ways to program a key fob, based on the vehicle's model and make. You can sometimes do this yourself, but most newer automobiles require an expert locksmith or dealer to program a replacement or additional fob. 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 then compares the data with the 'allowed signals' that are stored on the key fob and then it opens or closes the car door. If the information doesn't match the signals, the car will not be allowed to drive. Once the car has been paired with a specific fob, it can only receive signals from the device. This means that other fobs will not work with the vehicle, even though they have the same appearance. This protects the integrity of the car's computer system and to prevent the use of unauthorized key fobs to gain control over the vehicle. Most dealerships with newer cars will only work with cars that have original fobs, or genuine replacements offered by the manufacturer. This is because the process of creating the replacement fob is a process that requires technological and security skills that can only be found in the dealer service department. However, some aftermarket fobs typically for older models with less sophisticated systems can be programmed by consumers without the need of a dealership.
