Transponder Chips

If your car was manufactured in the past 20 years, then it has a transponder inside of it. This is the little plastic piece inside the head of your car key that houses an RFID (Radio Frequency ID) chip with a unique code for your car.

The chip emits a low-level radio signal when it is activated by an electromagnetic field. The signal is received by a specific antenna that is attached to the barrel of ignition. The computer system in the vehicle will then confirm that the key's transponder chip is the right one for your car.

A circuit within the induction coil will emit an electrical signal when the transponder is put into the ignition barrel. The signal is absorbed by the chip, which sends a signal to the vehicle. If the computer onboard the car detects the signal as valid it will turn off the vehicle immobilizer to allow the engine start.

If the vehicle does not recognize the transponder signal as being the correct one, it will keep the engine from running and will alert you by flashing its lights and sounding siren. This feature is intended to discourage people from attempting to hack into the vehicle, however it is not a foolproof security measure.

The receiver compares the information with the 'allowed signals' that are stored in the key fob, and then locks or opens the car's door. If the data doesn't match, a chirping sound is heard and the car isn't permitted to operate.

When a car is connected with a specific fob it will only receive signals from that specific device. In turn, other fobs will not work with the vehicle even if they appear similar. This helps to protect the integrity of the vehicle's computer system and prevent unauthorized key fobs from gaining control over the vehicle.

Most dealerships with newer cars will only deal with cars with original fobs or genuine replacements offered by the manufacturer. The reason for this is that the only place that has the knowledge to create an appropriate replacement fob is a 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 of dealers.
