Automotive key making has become very complicated over the past decade. There are several types of keys now in use with modern vehicles. There are proximity keys, transponder keys (Chipped) and VATS keys among others. Most of these keys now require a technician to connect to the vehicle with a special computer in order to make the vehicle accept the new key. Some cars even require a special pin code in order for the programming to be successful. Matters can become even more complicated if you lose all the existing keys. An automotive locksmith can navigate all these issues and make the process simple.
