Transponder Chips

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

When it is activated by an electromagnetic field the chip emits a low-level signal. This signal then gets absorbed by the special antenna that is fitted around the ignition barrel of your car. This allows the car's computer system to verify that the transponder chip inside the key is the right one for your particular car keys reprogramming.

This prevents the vehicle from starting by hot-wiring, or by tampering. The chip inside the key confirms that the owner is the person who owns the vehicle. This can reduce car theft.

When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil will send out the signal. The signal is absorbed by the chip, which sends a signal to the vehicle. If the computer on the car recognizes this signal as being the correct one, it will shut down the immobilizer on the vehicle and allow the engine to start.

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

When you press the button on a key fob the microchip sends a signal to the receiver in the car with which it is paired. The receiver compared this information to the 'allowed' signals in the fob and then either opens or closes the door. If the data does not match, the car will not be allowed to drive.

After the car has been connected to a specific fob, it can only receive signals from that device. Other fobs won't work with the car, even though they appear like. This protects the integrity of the computer system that runs the vehicle and stops unauthorized key fobs gaining control of it.

Most newer car dealers will only work on cars with original fobs or genuine replacements that are supplied by the manufacturer. It is because the only place with the expertise to prepare the replacement fob is the service department of the dealer. However, some aftermarket fobs that are typically designed for older models that have less sophisticated systems -- can be programmed by consumers without the need of an authorized dealer.
