Car key programming is the process of connecting an electronic car key fob to your vehicle so that it can open and start your car.

Transponder chips are used in modern cars to connect with the vehicle's system and identify the driver. The transponder is an unique coded message that the vehicle reads and recognizes to verify the authenticity of the key fob. To program a new key fob the vehicle has to match that unique code signal with the correct key fob. This can be accomplished using a special key programming tool, which communicates with the car in order to copy the current key and then transmits the code to a new fob. For certain vehicles it is possible that the EEPROM or module chip might need to be removed for programming. However other key programs can be created using the J2534 Interface.
Be sure to have two keys that function before you start reprogramming the car key. One key is required to connect the new car fob to your vehicle's system, and the second will be required to turn off and on your ignition. If you're not aware of the anti-theft features of your vehicle, it is a good idea to read the owner's manual for additional steps required by your car manufacturer to link a new key with your system. You can also search online for the model of your car and make sure you find instructions specific to your vehicle. Some auto repair shops or locksmiths can help you with the reconfiguration of your car's key fob in the event that it is required. Doing this will help you avoid damage to your car's electronics and help you save money on replacing your key with a costly one. Certain companies also offer a guarantee on their work and you can rest assured that your vehicle will be secure from any unauthorised access.
