Using a Key Programmer
Modern key fobs do more than simply function as keys. They communicate with the vehicle to turn it on, open the rear hatch, and more. To accomplish this they must be programmed to work with each other.
Car dealerships, your automobile manufacturer and auto key programmer locksmiths all offer key programming services. However, you can also do it yourself, if you have the proper equipment.
What is a key reprogramming programmer?
Key programmer is a device used to reprogram the transponder on the key of a truck or car key reprogrammed fob or key. This is required when the new key or program fob has to be programmed. It is also necessary when an existing key or fob has been stolen or lost. The device essentially reprograms the digital signature on the chip inside the key to match that of the vehicle and enable it to begin.
