It's a small plastic piece in the head of your key that houses a RFID (Radio Frequency Identification) chip with a unique code for the specific vehicle you own. When it is activated by an electromagnetic field, the chip emits a low-frequency signal. The signal is then absorbed by the special antenna that is attached to the ignition barrel of your vehicle. This allows the vehicle's computer system to determine if the transponder chip that is in the key is the correct one for your particular car. This is the reason why from modifying or hot-wiring the ignition system of the vehicle to get it started. The chip inside the key also proves that you are the genuine owner of the vehicle. This can reduce car theft. Regular transponder keys are designed like regular keys, but with a plastic top. The chip is inside the plastic portion of these keys. There are several different cuts such as a standard cut Laser cut (also known as a sidewinder or Ford Tibbe), and a Ford Tibbe. When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil sends out an electrical signal. The signal will be received by the chip and cause it to send a signal back to the car. If the car's computer detects this signal as the right one, it will disable the vehicle's immobilizer and allow the engine to start. If the vehicle does not recognize the transponder signal as the right one, it will prevent the engine from starting and will alert you by flashing its lights and sounding an alarm. This is designed to discourage people from trying to tamper with the vehicle, but it isn't a foolproof security measure.

These extra features can make it difficult for you to find your car keys. Key fobs make use of radio frequencies to communicate with one another and the car. These frequencies are transmitted via a small antenna that is located inside the middle of the key. The signal is encrypted to stop others from stealing or stealing the signal. You can program a keyfob in different ways based on the make and model of your car. You can sometimes do this yourself, but the majority of newer automobiles require a dealer or professional locksmith to program a replacement or a second fob. When you press the button on a key fob the microchip transmits signals to the receiver inside the vehicle with which it is paired. The receiver then compares this information with the signals that are allowed inside the fob, and either opens or closes the door. If the information does not match, the car will not be allowed to drive. Once the car is linked with a specific fob it will only accept signals from that specific device. Other fobs won't work with the car, even though they look similar. This is to safeguard the integrity of the vehicle's computer system and to prevent unauthorised key fobs from taking control of the vehicle. Most newer car dealerships will only accept cars that have original fobs, or genuine replacements supplied by the manufacturer. The reason for this is that the only place with the expertise to prepare the replacement fob is the service department of the dealer. 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 an authorized dealer.
