Transponder chips are used in modern cars to connect with the vehicle system and identify the driver. The transponder is a unique coded message that the vehicle reads and recognizes to confirm the authenticity of the key fob. To program a new key fob the vehicle needs to match the unique code signal with the correct key fob. This can be accomplished using an instrument for key programming, which communicates with the car to clone the current key, and then transmits the code to the new fob. For certain vehicles, the EEPROM or module chip might need to be removed in order to allow the reprogramming. However other key programs may also be made through a J2534 Interface. Before you begin the process of reprogramming your car key, be sure that you have two working keys in your possession. One key will be required to connect the new car fob to the car's system, while the second will be required to turn on and off your ignition.
