It does sound like the resolution of this problem will be with your dealer. Of course this is a busy time of year for dealers, and even in slow times, many dealers aren't all that responsive. But most likely someone at the dealership took the key out and used it to set up the safe. So they should be able to resolve this for you. If codes like 1-1-1-1 and 1-2-3-4 don't work, you'll have to keep after them.
