If the vehicle you're working on is a vehicle that has onboard programming, you can find out about it in the owner's manual or by searching the Internet for “onboard programming steps for X car.” In certain situations, the key will require cloning, which means that the new key needs to have the same immobilizer codes as the original one. This is accomplished using an instrument designed specifically for key programming that collects the code from the module and then burns it to the new key.
