Transponder chips can be found in vehicles manufactured within the last 20 years. It's the small plastic piece in the head of the car key that has an RFID (Radio Frequency ID) chip that has a unique code to your car.

When it is activated by an electromagnetic field the chip emits a low level signal. The signal is then taken up by the antenna that is positioned around the ignition barrel of your vehicle. This allows the vehicle's computer system to verify that the transponder chip inside the key is the correct one for the car you have.

This prevents the vehicle from starting by either hot-wiring or by altering the key. The chip inside the key also confirms that you are the legitimate owner of the vehicle. This will help reduce the possibility of theft from your vehicle.

When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil sends out an electrical signal. The signal will then get taken up by the chip and cause it to send a signal back to the car. If the computer in the car recognizes the signal as being correct it will turn off the vehicle immobilizer so that the engine can start.

If the car does not recognize the transponder signal as the proper one, it will stop the engine from starting and will notify you by flashing its lights and sounding a siren.

The receiver compared the information with the 'allowed signals' that are stored on the key fob and then it opens or closes the car key programing's doors. If the data doesn't match an chirping sound is heard and the car isn't allowed to function.

After the car has been connected to a specific fob, it can only receive signals from that device. Other fobs will not work with the car, even if they look identical. This protects the integrity of the computer system that runs the car and prevents unauthorized key fobs gaining control over it.

The majority of newer dealerships will only work with cars that have original fobs, or genuine replacements offered by the manufacturer. This is because the process of creating a replacement fob requires technological and security expertise that is only available in the dealer's service department. However, some aftermarket fobs -- usually those for older models that have less sophisticated systems can be programmed by customers without the need for dealers.
