and if it's that specific lock, be thankful you were able to get back in without a major project.
The exact model lock in question is a couple posts down. If you gOOgle that part number you can see if that's the one you have. If it is, suggest replacement with a different brand.

Yikes, thanks for this post. Our door lock has not worked since we bought the rig. We always use the cab doors. The lock has both a keyed lock and an unkeyed deadbolt. Both only work from inside-the key does not turn the lock.
Never thought the bolt could break in the locked position though! Something else that we may need to replace? I'll check the brand to see if it matches the troubled one or if the sticking lock problem is universal too. (Like cab over leaks!)
