Transponder Chips

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

When activated by an electro-magnetic field, the chip emits a low-level signal. This signal is then absorbed by a special antenna that is attached to the ignition barrel. The computer system of the vehicle can then verify that the transponder chip of the key is the correct one for your vehicle.

This is what prevents hot-wiring or tampering with the ignition system of your vehicle to get it started. The chip in the key also verifies that you are the legal 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 inside of the induction coil sends out an electrical signal. The signal is received by the chip which then transmits a signal the vehicle. If the computer onboard the car Key reprogram detects the signal as valid, it will disable vehicle immobilizer, allowing the engine to start.

If the vehicle does not recognize the transponder signal as the proper one, it will stop the engine from running and will notify you by flashing its lights and sounding an alarm.

The receiver compares this information with the 'allowed' signals stored inside the fob, and either opens or locks the door. If the data doesn't match an chirping sound is heard and the car isn't permitted to operate.

Once the car has been connected to a specific fob, it only accepts signals from that device. Other fobs won't work with the car, despite the fact that they look identical. This is to safeguard the integrity of the car's computer system and to prevent unauthorised key fobs from taking control over the vehicle.

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