I kind of hate to remind you that the more information we have the better the answers you will get. What door lock do you have and is there any marking on the bezel around the keyway?
The guys from AAA are generally not locksmiths, have you called a professional locksmith?
My RV has a TriMark entry with a dead bolt built in. Takes two keys to open. My local locksmith said he can get in in just a few minutes.
Winnie keeps a record of all the keys in use, I can get it by calling them or by the series number on the keys which evidently you don't have but maybe Coachmen keeps records.
Try searching for anything relating to being locked out listed here on the forums, use the name of the lock system. Lots of info here but sometimes it requires just the right search parameters.
Good Luck and enjoy your 4 day week-end, I know you'll get in.
