We were locked in our class A MH once, and only one door.
Called a dealer where we were and they said to come in when we got there. I told her that we could not get out. So I called when we arrived and three service guys came out with huge smiles on their faces. Two helped the third to climb in out dinette window, he had them bring out a drill and he got the door open.
I purchased a new lock from them and installed it myself. They did not charge me anything to "break us out."
The dealer was Tennessee RV just off I-40 East side of Knoxville. Good folks.
