Transponder Chips Transponder chips can be found in vehicles manufactured within the last 20 years. It's a tiny plastic thing on the back of your key which contains an RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle. The chip sends out a low-level radio signal when it is activated by an electromagnetic field. The signal is absorbed by a special antenna that is attached to the ignition barrel. The computer system of the vehicle will then confirm that the key's transponder chip is the right one for your car. This is what prevents from modifying or hot-wiring the ignition system of your vehicle to turn it on. The chip inside the key also confirms that you are the genuine owner of the vehicle. This will help reduce car theft. Transponder keys look like regular keys made of metal but have caps made of plastic. The chip is housed within the plastic part of the key, and there are a few different kinds of cuts available on these keys: a regular standard cut, a laser cut (also known as a sidewinder key), or a Ford Tibbe key. When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil sends out a signal. The signal is absorbed by the chip, which then transmits a signal the vehicle. If the car's computer detects this signal as the correct one, it will shut down the immobilizer on the vehicle and allow the engine to start. If the car does not recognize the transponder signal as the right one, it will prevent the engine from starting and will notify you by flashing its lights and sounding siren. This feature is designed to discourage people from trying to hack into the vehicle, however it is not a foolproof security measure. A determined and skilled thief can still get around this system with a specially designed device that detects the signal. It is evident that a transponder is a great option.

Key Fobs Key fobs today can do more than just lock and unlock doors. They can also start the vehicle from a distance, make chirping sounds to aid in finding the car or turn on the heated steering wheel. These extra features can 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 through a small antenna located within the middle of the key. The communication is encrypted, which helps keep others from stealing and re-transmitting the signal. You can program a keyfob in various ways based on the model and make of your vehicle. You may be able to do it yourself, but the majority of newer automobiles require an expert locksmith or dealer to program a replacement or a second fob. When you press the button on a key fob the microchip sends a signal to the receiver inside the vehicle that it is paired. The receiver then compares this information to the 'allowed' signals stored on the fob and either opens or closes the door. If the data does not match, the car will not be allowed to operate. After the car has been paired with a specific fob, it can only receive signals from that device. This means that other fobs won't be able to work with the vehicle, even though they appear similar. This protects the integrity of the car's computer system and to prevent unauthorized key fobs from gaining control of the vehicle. Most newer car dealers will only work on a car with original fobs or genuine replacements sold by the manufacturer. This is because the process of creating a replacement fob requires technological and security expertise 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 the consumer without the need for an authorized dealer.
