Transponder Chips

If your car was manufactured within the last 20 years, then it contains a transponder chip within of it. It's a small piece of plastic on the back of your key which contains an RFID (Radio Frequency Identification) chip with an individual code for your particular vehicle.

The chip sends out an low-level radio signal once it is activated by an electromagnetic field. The signal is then taken up by an antenna that is attached to the ignition barrel. This allows the computer in your vehicle system to determine if the transponder chip that is in the key is the right one for your particular car.

This prevents the vehicle from being started by hot-wiring, or by manipulating. The chip in the car key ensures that the owner is the one who is the owner of the vehicle. This can help to reduce the possibility of theft from your vehicle.

The circuit in the induction coil emits an electrical signal when the transponder is inserted into the ignition barrel. The signal will be absorbed by the chip and cause it to transmit a signal back to the car. If the computer inside the car recognizes the signal as being correct it will turn off the car immobilizer so that the engine can start.

If the car doesn't recognize the transponder as the correct signal, it won't start the engine, and will warn you with flashing lights and a siren. This feature is designed to discourage people from tampering with the vehicle. However it isn't an absolute security measure. A skilled and determined criminal may still be able to get around this system using a special device to detect the signal.

There are many ways to program a key fob, based on your vehicle's make and model. 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 your key fob, the microchip inside transmits an informational code to the car's receiver it is linked to. The receiver compared this information with the 'allowed' signals stored in the fob and then either opens or closes the door. If the information isn't in line an chirping sound is heard and the car isn't able to operate.

When a car is connected with a specific fob, it will only receive signals from that device. Other fobs will not work with the car, even if they look similar. This ensures the security of the computer system that runs the car and prevents unauthorized key fobs gaining control of it.

The majority of newer dealers will only work on cars with original fobs or genuine replacements supplied by the manufacturer. This is because the process of creating the replacement fob is a process that requires technological and security expertise that can only be found in the dealer's service department. Certain aftermarket fobs, typically those from older models that have less advanced systems can be programmed without the need for a dealership.
