Transponder Chips

Transponder chips can be found in vehicles manufactured within the last 20 years. It's the tiny piece of plastic in the head of the car key that has an RFID (Radio Frequency ID) chip that has a unique code to the vehicle you own.

When activated by an electro-magnetic field the chip emits a low level signal. This signal is then taken up by an antenna that is attached to the ignition barrel. This allows the car's computer system to verify that the transponder chip in the key is the correct one for the car you have.

This stops the vehicle from being started through either hot-wiring or by altering the key. The chip in the key also proves that you are the genuine owner of the vehicle. This helps to reduce the risk of theft from your car.

Transponder keys appear like regular keys made of metal but they have a plastic cap. The chip itself is housed in the plastic portion of the key and there are different types of cuts on the keys: a cut, a laser cut (also called a sidewinder key), or a Ford Tibbe key.

When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil will send out an electrical signal. The signal is received by the chip which then transmits a signal the vehicle. If the computer onboard the car is able to recognize the signal as being correct it will turn off the vehicle immobilizer, allowing the engine to start.

If the vehicle does not recognize the transponder signal as being the proper one, it will stop the engine from starting and will notify you by flashing its lights and sounding a siren. This function is designed to discourage those who would attempt to alter the vehicle. However it's not an unbreakable security measure. A determined and skilled thief could still evade this system using a special device that blocks the signal.

Key Fobs

A lot of these features might seem useful however they could make it harder for you to keep the keys to your car.

Key fobs communicate with one with the car via radio frequencies that are transmitted via an antenna that is located in the middle of the key. This communication is encrypted to prevent others from intercepting or replicating the signal.

There are a few different ways to program a key fob depending on the make and model. It is possible to do this yourself, however most modern automobiles require an expert locksmith or dealer to program a replacement or an additional fob.

When you hit the button on a key fob the microchip inside sends an informational code to the car's receiver it is paired with. The receiver compares this information with the 'allowed' signals stored inside the fob, and either opens or locks 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 accept signals from that device. Other fobs won't work with the car, even though they appear similar. This ensures the security of the computer system in the car and blocks unauthorised key fobs from taking control over it.

Most dealerships with newer cars will only accept cars that have original fobs, or genuine replacements sold by the manufacturer. The reason for this is that the only place that has the experience to design a replacement fob is in the service department of the dealer. Certain aftermarket fobs, typically those for older models with less advanced systems, can be programmed without the need for a dealership.
