Transponder Chips If your car is made within the past 20 years, then it has a transponder inside of it. It's a tiny plastic piece on the back of your key that contains an RFID (Radio Frequency Identification) chip with a unique code that is specific to your specific vehicle. The chip emits an low-level radio signal once it is activated by an electromagnetic field. The signal is taken up by an antenna that is attached to the ignition barrel. This allows the computer in your vehicle system to verify that the transponder chip that is in the key is the correct one for your specific vehicle. This is what prevents doing hot-wiring or altering the ignition system of the vehicle to start it. The chip inside the car key ensures that the owner is the one who owns the vehicle.

There are a variety of cuts such as a standard cut laser cut (also called a sidewinder or Ford Tibbe), and a Ford Tibbe. The circuit in the induction coil emits a signal when the transponder is put into the ignition barrel. The signal will then get received by the chip, causing it to send a signal back to the car. If the computer inside the car recognizes the signal as valid, it will disable vehicle immobilizer to allow the engine start. If the vehicle does not recognize the transponder signal as being the right one, it will keep the engine from starting and will alert you by flashing its lights and sounding siren. This is designed to discourage people from trying to tamper with the vehicle, however it is not a foolproof security measure.

Certain cars let you do this yourself. However, the majority of modern models require you to visit a professional locksmith or dealer for them program a replacement key fob or additional one. When you hit the button on a key fob it transmits a code to the car's radio that it is paired with. The receiver compared this information to the signals that are allowed inside the fob, and either locks or opens the door. If the data doesn't match an chirping sound is heard and the car isn't able to operate. Once the car is linked with a particular fob, it will only receive signals from the device that is associated with it. In turn, other fobs won't work with the vehicle even if they appear similar. This is to safeguard the integrity of the vehicle's computer system and prevent the use of unauthorized key fobs to gain control of the vehicle. Most dealerships with newer cars will only deal with cars with original fobs or genuine replacements sold by the manufacturer.
