Transponder Chips
If your car is made in the last 20 years, chances are it has a transponder inside of it. It's a small piece of plastic inside the head of your key that houses an RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.
The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. reprogram car key gets absorbed by the special antenna that is fitted around the barrel that controls your ignition in your vehicle. The computer system of the vehicle will then confirm that the chip in the key's transponder is the correct one for your car.
This stops the vehicle from being started through hot-wiring, or by manipulating. The chip in the key also verifies that you are the genuine owner of the vehicle. This can help to reduce the possibility of theft from your vehicle.

A circuit within the induction coil will emit a signal when the transponder is inserted into an ignition barrel. The signal is absorbed by the chip, which sends a signal to the vehicle. If the onboard car computer recognizes this signal as the correct one, it will shut down the immobilizer on the vehicle and allow the engine to begin.
If the vehicle doesn't recognize the transponder signal as being the correct one, it will prevent the engine from running and will notify you by flashing its lights and sounding a siren. This feature is designed to discourage individuals from tampering with the vehicle. However, it is not a foolproof measure of security.

Key Fobs
In addition to locking and unlocking doors, launching the car from a distance or making chirping sounds to help find a car in a parking space, today's key fobs can also switch on a heated steering wheel or roll down all windows with a single button push. Many of these extra features may seem convenient but they could make it harder for you to keep the track of your car keys.
Key fobs utilize radio frequencies to communicate with each other and the car. The frequencies are transmitted through a small antenna located inside the middle of the key. The signal is encrypted to block other key fobs from intercepting or replicating the signal.
You can program a keyfob in different ways based on the model and make of your vehicle. You can sometimes do this yourself, but the majority of newer vehicles require a locksmith shop or a professional to program a replacement or additional fob.
When you press the button on a key fob the microchip sends an indication to the receiver inside the car with which it is linked. The receiver compares this information with the 'allowed' signals stored on the fob and either opens or closes the door. If the data doesn't match an chirping sound is heard and the car isn't allowed to function.
Once the car is associated with a particular fob, it only accepts signals from that device. Other fobs will not work with the car, even if they look similar. This safeguards the integrity of the computer system that runs the car and blocks the use of unauthorized key fobs to gain control over it.
The majority of newer dealerships will only work with vehicles that have original fobs, or genuine replacements offered by the manufacturer. This is because the only place with the expertise to prepare an appropriate replacement fob is the service department of the dealer. Some fobs from the aftermarket, especially ones for older models that have less sophisticated systems can be programmed without the need for a dealership.
