Transponder Chips

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

When activated by an electro-magnetic field, the chip emits a low-frequency signal. The signal is then received by a specific antenna that is attached to the ignition barrel. This allows the car's computer system to determine if the transponder chip inside the key is the correct one for the car you have.

The receiver compares this information with the signals that are allowed in the fob and then either opens or closes the door. If the information doesn't match the signals, the car will not be allowed to operate.

Once the car is paired with a specific fob it will only receive signals from the device that is associated with it. Other fobs will not work with the car, despite the fact that they appear like.
