Transponder Chips

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

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

When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil sends out the signal. The signal is received by the chip which sends a signal to the vehicle. If the computer inside the car recognizes the signal as valid it will turn off the car immobilizer to allow the engine start.

If the car isn't able to recognize the transponder as the correct signal, it will not start the engine and will alert you with flashing lights and siren. This feature is designed to discourage people from tampering with the vehicle. However, it is not an absolute security measure. A skilled and committed thief may still be able to get around this system employing a device designed to detect the signal.

When you press a key fob's button it transmits an informational code to the car's receiver it is paired with. The receiver compared the information with the permitted signals stored in the key fob and then locks or opens the car's doors. If the data doesn't match, a chirping sound is heard and the car isn't able to operate.

Once the car is connected to a specific fob, it will only accept signals from that device. Other fobs won't work with the car, even if they appear like. This protects the integrity of the computer system in the car and prevents the use of unauthorized key fobs to gain control over it.

Most newer car dealers will only work on cars with original fobs or genuine replacements that are offered by the manufacturer.
