We no longer have stock of the Sharp Service Key however we can make them from a Sharp programming key. We will create a key and test it before shipping if you need a service key. The service key is not the standard programming key. The service key accesses factory level programming and is rarely required by an end-user. There are certain settings that can only be accomplished with the service key. Please allow a few days for the item to be shipped as we have to custom cut a key.
