Transponder Chips

If your car is made in the past 20 years, chances are it has a transponder chip inside of it. This is the little piece of plastic in the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to the vehicle you own.

The chip sends out a low-level radio signal when it is activated by an electromagnetic field. The signal is taken up by an antenna attached to the barrel of ignition. The computer system of the vehicle will then confirm that the key's transponder chip is the correct one for your car.

This stops the vehicle from being started through hot-wiring, or by tampering. The chip inside the key also verifies that you are the legitimate owner of the vehicle. This can reduce car theft.

When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil sends out the signal. The signal will be taken up by the chip, causing it to send a signal back to the car. If the onboard car computer recognizes this signal as the correct one, it will shut down the immobilizer on the vehicle and allow the engine to begin.


If the car isn't able to recognize the transponder as a valid signal, it will not start the engine and will notify you via flashing lights and siren. This feature is designed to discourage those who would attempt to alter the vehicle. However it's not an absolute security measure.

When you press a key fob's button, the microchip inside transmits a code to the car's receiver that it is paired with. The receiver then compares the data with the permitted signals stored on the key fob and then locks or opens the car's door. If the information isn't in line, a chirping sound is heard and the car isn't allowed to operate.

Once the car has been paired with a specific fob, it can only receive signals from that device. As a result, other fobs won't work with the vehicle even though they look the same. This protects the integrity of the computer system that runs the vehicle and stops the use of unauthorized key fobs to gain control of it.
