Transponder Chips

Transponder chips can be found in cars manufactured in the last 20 years. It’s a small piece of plastic in the head of your key which contains an RFID (Radio Frequency Identification) chip with an individual code for your particular vehicle.

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

When the transponder key is placed in the ignition barrel, a circuit within of the induction coil will send out the signal. The signal will then get received by the chip and cause it to send a signal back to the car. If the onboard car computer recognizes this signal as the right one, it will shut down the vehicle immobilizer and allow the engine to start.

If the car isn’t able to recognize the transponder as a valid signal, it won’t start the engine and will warn you with flashing lights and siren. This system is designed to deter individuals from tampering with the vehicle. However, it is not an unbreakable security measure.

When you press a key fob’s button it transmits an informational code to the car’s radio that it is paired with. The receiver compared this information to the ‘allowed’ signals inside the fob, and either locks or opens the door. If the information doesn’t match the signals, a chirping sound can be heard and the car isn’t allowed to operate.

Once the car is paired with a particular fob, it will only accept signals from the device that is associated with it. This means that other fobs won’t work with the vehicle even if they appear similar. This is to safeguard the integrity of the car’s computer system and prevent unauthorised key fobs from taking control of the vehicle.

The majority of newer dealerships will only deal with vehicles that have original fobs or genuine replacements offered by the manufacturer. This is because preparing the replacement fob is a process that requires technological and security knowledge that is only available in the dealer’s service department. Some fobs from the aftermarket, especially ones for older models with less sophisticated systems can be programmed without the need for a dealer.
