Transponder Chips

If your car is made within the past 20 years, chances are it has a transponder chip inside of it. This is the little plastic piece in the head of your car key that contains an RFID (Radio Frequency ID) chip that has a unique code to your car.

When activated by an electro-magnetic field the chip emits a low-frequency signal. The signal is then taken up by the antenna that is fitted around the ignition barrel of your vehicle. The computer system of the vehicle will then confirm that the transponder chip of the key is the correct one for your car.

This stops the vehicle from being started by hot-wiring or manipulating. The chip in the car key ensures that the owner is the one who owns the vehicle. This helps to prevent the possibility of theft from your vehicle.

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 several different cuts: a standard cut and program car key, Laser cut (also called a sidewinder or Ford Tibbe), and Ford Tibbe.

A circuit within the induction coil will emit signals when the transponder is put into the ignition barrel. The signal is absorbed by the chip, which then transmits a signal the vehicle. If the computer inside the car detects the signal as correct it will turn off the vehicle immobilizer, allowing 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 a siren. This is designed to discourage people from trying to hack into the vehicle, but it is not a foolproof security measure. A skilled and determined thief could still be able to escape this security system by using a device that can detect the signal.

A lot of these additional features may appear convenient however they could make it difficult for you to keep track of your car keys.

Key fobs communicate with one with the car key cut and programed via radio frequencies that are transmitted via a small antenna located in the center of the key. The communication is encrypted, which helps stop others from stealing and replicating the signal.

There are many ways to program a key fob, based on your vehicle's model and make. You may be able to do it yourself, but most newer automobiles require a dealer or professional locksmith to program a replacement or additional fob.

When you press the button on a key fob the microchip transmits an indication to the receiver inside the vehicle with which it is linked. The receiver compared the information with the 'allowed signals' stored in the key fob and then locks or opens the car's door. If the information doesn't match the fob's information, the car won't be allowed to operate.

Once the car is linked with a specific fob it will only accept signals from that specific device. In turn, other fobs won't work with the vehicle even though they appear similar. This safeguards the integrity of the computer system that runs 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 that are offered by the manufacturer. It is because the only place that has the experience to design an appropriate replacement fob is a dealer's service department. Certain aftermarket fobs, typically ones for older models that have less sophisticated systems can be programmed with out the need for a dealership.
