Transponder Chips

If your car was built within the past 20 years, it is likely that it has a transponder inside of it. It's the small piece of plastic in the head of your car key that houses an RFID (Radio Frequency ID) chip that has a unique code to the vehicle you own.

The chip emits an low-level radio signal once it is activated by an electromagnetic field. This signal is then taken up by the antenna that is attached to the barrel that controls your ignition in your vehicle. This allows the vehicle's computer system to determine if the transponder chip in the key is the right one for your particular car.

This is what stops from modifying or hot-wiring the ignition system of the vehicle to get it started. The chip inside the key also verifies that you are the genuine owner of the vehicle. This helps to reduce the risk of theft from your car.

When the transponder key is placed in the ignition barrel, a circuit within of the induction coil will send out an electrical signal. The signal will be received by the chip, causing it to send a signal back to the car. If the car's computer recognizes this signal as the right one, it will disable the vehicle immobilizer and allow the engine to begin.

If the vehicle doesn't recognize the transponder as being the proper signal, it won't start the engine, and will alert you with flashing lights and a siren. This system is designed to deter individuals from tampering with the vehicle. However, it is not a foolproof measure of security. A skilled and determined criminal may still be able to bypass this system by using a device that can detect the signal.

The receiver compares this information with the 'allowed' signals stored on the fob and either locks or opens the door. If the data doesn't match the signals, a chirping sound can be heard and the car isn't permitted to function.

After the car keys programmed has been associated with a particular fob, it can only receive signals from that device. As a result, other fobs won't work with the vehicle even if they have the same appearance.
