Years ago, in a campground. We had a Pace Arrow 34ft. A neighbor kid was in our coach and locked the door on his way out. We were having a fire and the kids wanted smores. So my daughter who was 11 at the time couldn't get in. I didn't have a key etc, no windows open. I went up on the roof and took a vent off and lowered my daughter thru the vent. She grabbed the smores and came out. I know it doesn't help you, but it's a great memory for me. My daughter is 22 now and graduates from the university next sat.
Good luck with your issue, and your camper is awesome.
