Transponder Chips

If your car is made within the past 20 years, then it has a transponder inside of it. It's a small plastic thing in the head of your key that houses an RFID (Radio Frequency Identification) chip with a unique code for your particular vehicle.

The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. This signal is then taken up by an antenna attached to the ignition barrel. This allows the car's computer system to confirm that the transponder chip in the key is the correct one for your specific vehicle.

This stops the vehicle from being started by either hot-wiring or by manipulating. The chip in the key also confirms that you are the legal owner of the vehicle. This will help reduce car theft.

Transponder keys appear like regular keys made of metal but have a plastic cap. The chip is housed in the plastic portion of the key, and there are different kinds of cuts available on these keys: a cut, a laser cut (also known as a sidewinder programing key), or a Ford Tibbe key.

When the transponder key programing is inserted into the ignition barrel, a circuit within of the induction coil will send out a signal. The signal will be absorbed by the chip and cause it to send a signal back to the car key reprogramming. If the computer in the car detects the signal as correct it will turn off the vehicle immobilizer so that the engine can start.

If the car doesn't recognize the transponder as a valid signal, it won't start the engine, and will notify you via flashing lights and siren. This is designed to discourage people from attempting to hack into the vehicle, however it isn't a foolproof security measure. A skilled and determined thief could still evade this system with a specially designed device that intercepts the signal.

Key fobs communicate with each with the car via radio frequencies which are transmitted by an antenna in the middle of the key. This signal is encrypted to stop others from intercepting or 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 the majority of newer cars require that you visit a dealer or professional locksmith to program a replacement or an additional fob.

When you press the button on a key fob key programmer, the microchip sends a signal to the receiver inside the vehicle with which it is paired. The receiver then compares this information with the signals that are allowed on the fob and either opens or closes the door. If the information isn't in line the signals, a chirping sound can be heard and the car isn't permitted to function.

Once the car is associated with a particular fob, it can only receive signals from the device. In turn, other fobs won't be able to work with the vehicle even if they appear similar. This helps to protect the integrity of the vehicle's computer system and to prevent unauthorized key fobs from gaining control over the vehicle.

Most dealerships with newer cars will only accept vehicles that have original fobs or genuine replacements offered by the manufacturer. This is because the process of creating an appropriate replacement fob requires technical and security knowledge that can only be found in the dealer service department. However, some fobs from the aftermarket typically for older models with less sophisticated systems -- can be programmed by consumers without the need of a dealership.
