Transponder Chips

If your car is made within the last 20 years, it is likely that it contains a transponder chip within of it. It's a small plastic thing inside the head of your key which contains an RFID (Radio Frequency Identification) chip with a unique code that is specific to the specific vehicle you own.

When it is 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 ignition barrel of your car. This allows the computer in your vehicle system to confirm that the transponder chip that is in the key is the right one for your specific vehicle.

This prevents the vehicle from starting by hot-wiring, or by altering the key. The chip inside the car key ensures that the owner is the person who is the owner of the vehicle. This can reduce car theft.

Regular transponder keys are designed like regular keys and have an outer layer of plastic. The chip is housed inside the plastic portion of the key and there are a few different cuts that can be found on the keys: a cut laser cut (also known as a sidewinder key) or Ford Tibbe key.

A circuit inside the induction coil will emit an electrical signal when the transponder is placed in the an ignition barrel. The signal is taken up by the chip, which then transmits a signal to the vehicle. If the computer onboard the car is able to recognize the signal as correct it will turn off the car immobilizer so that the engine can start.

If the vehicle does not recognize the transponder signal as the right one, it will prevent the engine from running and will alert you by flashing its lights and sounding siren. This feature is intended to discourage people from attempting to hack into the vehicle, however it isn't a foolproof security measure. A determined and skilled thief could still bypass this system with a specially designed device that blocks the signal.

Key Fobs

In addition to locking and unlocking doors, starting the car key programing remotely, or making chirping sounds to help find a car in a parking space Key fobs today can also switch on a heated steering wheel, or roll down all of the windows with a single button push. These additional features could make it difficult to find your car keys.

Key fobs make use of radio frequencies to communicate with each other and with the car. These frequencies are sent through a small antenna located in the middle of the key. The communication is encrypted, which helps keep others from stealing and retransmitting the signal.

There are several ways to program a key fob based on your vehicle's model and make. It is possible to do this yourself, but the majority of newer cars require that you visit a locksmith shop or a professional to program a replacement or an additional fob.

When you press the button on a key fob the microchip transmits an indication to the receiver in the car that it is paired. The receiver compared this information to the 'allowed' signals stored inside the fob, and either opens or locks the door. If the information doesn't match, the car key cutting and programming will not be allowed to drive.

Once the mobile car key programming is linked with a particular fob, it will only receive signals from that specific device. This means that other fobs will not work with the vehicle, even though they look the same. This ensures the security of the computer system of the car and blocks unauthorized key fobs gaining control over it.

Most newer car dealerships will only deal with cars with original fobs, or genuine replacements offered by the manufacturer. This is due to the fact that preparing an appropriate replacement fob requires technical and security expertise that is only available in the dealer service department. However, some fobs from the aftermarket -- usually those for older models that have less sophisticated systems can be programmed by the consumer without the need of a dealership.
