This is a little piece of plastic in the head of your key that contains a RFID (Radio Frequency Identification) chip with a unique code for the specific vehicle you own.When it is activated by an electro-magnetic field the chip emits a low-frequency signal. This signal then gets taken up by the antenna that is positioned around the ignition barrel of your car. The computer system in the vehicle can then verify that the key’s transponder chip is the correct one for your car.This prevents the vehicle from being started through hot-wiring or tampering. The chip inside the key also proves that you are the legitimate owner of the vehicle. This will help reduce car theft.Regular transponder keys are designed like regular keys, but with a plastic top. The chip is contained within the plastic part of the keys. There are a variety of cuts such as a standard cut laser cut (also known as a sidewinder or Ford Tibbe), and Ford Tibbe.When the transponder key is placed in the ignition barrel, a circuit within of the induction coil will send out an electrical signal. The signal will then get absorbed by the chip, causing it to transmit a signal back to the car. If the computer on the car detects this signal as the right one, it will shut down the immobilizer on the vehicle and allow the engine to start.If the vehicle doesn’t recognize the transponder as being the proper signal, it won’t start the engine and notify you via flashing lights and an alarm. This feature is designed to discourage people from trying to alter the vehicle, however it is not a foolproof security measure.

This communication is encrypted, which helps prevent others from intercepting and re-transmitting the signal.There are several ways to program a key fob based on the model and make. Some cars allow you to do this by yourself. However, the majority of newer models require you to visit an expert locksmith or dealer in order for them program a replacement key fob or additional one.When you press the button on your key fob it transmits an encoded code to the car’s receiver that it is linked to. The receiver then compares this information with the ‘allowed’ signals stored on the fob and either opens or locks the door. If the information doesn’t match, a chirping sound is heard and the car isn’t able to function.Once the car is paired with a particular fob, it will only receive signals from that specific device. Other fobs won’t work with the car, even if they look like. This protects the integrity of the car’s computer system and to prevent unauthorised key fobs from taking control of the vehicle.Most dealerships with newer cars will only deal with cars that have original fobs, or genuine replacements offered by the manufacturer. This is because the only place that has the experience to design a replacement fob is in the service department of a dealer. However, some aftermarket fobs that are typically designed for older models with less sophisticated systems — can be programmed by the consumer without the need of a dealership.
