Transponder Chips
Transponder chips are likely to be found in cars that were manufactured in the last 20 years. 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 that is specific to your particular vehicle.
The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. The signal is then absorbed by the special antenna that is attached to the ignition barrel of your vehicle. This allows the computer in your vehicle system to confirm that the transponder chip that is in the key is the right one for your particular car.
This stops the vehicle from being started through either hot-wiring or by tampering. The chip inside the car key ensures that the owner is the person who is the owner of the vehicle. This helps to reduce the risk of theft from your car.
Regular transponder keys are shaped like regular keys, but with a plastic top. The chip is contained within the plastic part of the key, and there are different cuts that can be found on these keys: a cut laser cut (also known as a sidewinder key), or a Ford Tibbe key.
A circuit inside the induction coil will emit an electrical signal when the transponder is put into an ignition barrel. The signal is taken up by the chip, which then transmits a signal to the vehicle. If the computer in the car detects the signal as correct, it will disable vehicle immobilizer so that the engine can start.
If the vehicle doesn't recognize the transponder signal as being the correct one, it will keep the engine from starting and will notify you by flashing its lights and sounding siren. This feature is designed to discourage people from attempting to tamper with the vehicle, however it is not a foolproof security measure. A skilled and determined thief could still bypass this system with a specially designed device that intercepts the signal.

Keyfobs can be programmed in a variety of ways depending on the make and model of your vehicle. You may be able to do it yourself, but the majority of newer cars require that you visit a dealer or professional locksmith to program a replacement or an additional fob.
When you press the button on your key fob, the microchip inside transmits an informational code to the car's receiver it is linked to. The receiver compares this information with the 'allowed' signals stored on the fob and either opens or locks the door. If the information isn't in line an chirping sound is heard and the car isn't allowed to operate.
After the car has been paired with a specific fob, it will only accept signals from the device. This means that other fobs will not work with the vehicle, even though they appear similar. This helps to protect the integrity of the vehicle's computer system and prevent the use of unauthorized key fobs to gain control of the vehicle.
The majority of newer dealerships will only work with vehicles that have original fobs or genuine replacements supplied by the manufacturer. This is because preparing an appropriate replacement fob requires technical and security expertise that is only available in the dealer service department. However, some aftermarket fobs typically for older models that have less sophisticated systems -- can be programmed by customers without the need for dealers.
