Transponder Chips
If your car was built in the past 20 years, chances are it has a transponder chip inside of it. This is the little plastic piece inside the head of your car key that houses an RFID (Radio Frequency ID) chip that has a unique code to the vehicle you own.
When it is activated by an electromagnetic field the chip emits a low-frequency signal. This signal is then absorbed by a special antenna that is attached to the barrel of ignition. The computer system of the vehicle is then able to verify that the chip in the key's transponder is the right one for your car.
This prevents the vehicle from being started by hot-wiring, or by tampering. The chip in the key also proves that you are the genuine owner of the vehicle. This will help reduce car theft.

The circuit in the induction coil will emit signals when the transponder is inserted into an ignition barrel. The signal is absorbed by the chip, which then transmits a signal the vehicle. If the computer inside the car recognizes the signal as being correct, it will disable vehicle immobilizer to allow the engine start.
If the vehicle doesn't recognize the transponder signal as being the proper one, it will keep the engine from running and will alert you by flashing its lights and sounding siren.

There are several ways to program a key fob based on the vehicle's make and model. You can sometimes do this yourself, but the majority of newer vehicles require a locksmith shop or a professional 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 in the vehicle with which it is linked. The receiver then compares this information to the 'allowed' signals on the fob and either opens or closes the door. If the data doesn't match, a chirping sound is heard and the car isn't able to operate.
Once the car is paired with a specific fob, it only accepts signals from the device. Other fobs will not work with the car, despite the fact that they appear identical. This helps to protect the integrity of the vehicle's computer system, and also to stop the use of unauthorized key fobs to gain control over the vehicle.
The majority of newer dealers will only work on a car with original fobs or genuine replacements supplied by the manufacturer. This is because the process of creating an appropriate replacement fob requires technical and security knowledge that can only be found in the dealer service department. However, some aftermarket fobs -- usually those for older models that have less sophisticated systems -- can be programmed by the consumer without the need for dealers.
