Transponder Chips

Transponder chips can be found in vehicles manufactured in the last 20 years. This is the little piece of plastic in the head of the car key that has an RFID (Radio Frequency ID) chip with a unique code for your vehicle.

When it is activated by an electro-magnetic field, the chip emits a low-level signal. The signal is then taken up by an antenna that is attached to the barrel of ignition. The computer system in the vehicle will then confirm that the transponder chip of the key is the correct one for your vehicle.

This is what prevents from modifying or hot-wiring the vehicle's ignition system to start it. The chip inside the key also verifies that you are the genuine owner of the vehicle. This helps to prevent car theft.

Regular transponder keys are shaped like regular keys and have a plastic top. The chip is contained within the plastic portion of these keys. There are a variety of cuts that are a standard cut, laser cut (also known as a sidewinder or Ford Tibbe), and the Ford Tibbe.

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

If the vehicle does not recognize the transponder signal as the proper one, it will prevent the engine from starting and will alert you by flashing its lights and sounding a siren. This system is designed to deter those who would attempt to alter the vehicle. However, it is not an absolute security measure. A determined and skilled thief can still get around this system with a specially designed device that blocks the signal.

There are a few different ways to program a key fob based on your vehicle's make and model. Certain cars let you do this yourself. However, most newer models require you to visit an expert locksmith or dealer to program a new key fob, or an alternative one.

When you press the button on your key fob the microchip inside sends an encoded code to the car's receiver it is paired with. The receiver compared this information with the 'allowed' signals stored in the fob and then either opens or closes the door. If the information does not match, the car will not be allowed to run.

Once the car is linked with a specific fob it will only receive signals from the device that is associated with it. This means that other fobs won't work with the vehicle, even though they have the same appearance. This safeguards the integrity of the computer system of the car and blocks unauthorised key fobs from taking control of it.

Most newer car dealers will only work on cars with original fobs or genuine replacements sold by the manufacturer. This is because the only place that has the experience to design an appropriate replacement fob is the service department of a dealer. Some fobs from the aftermarket, especially ones for older models with less advanced systems can be programmed with out the need for a dealership.
