LOL, we did this to our DS in 2012, DW and I left for the parks for the day, I locked the handle lock on the camper, DS came out from inside, slammed the door shut and couldn't get back in. He went to office, of course, they tried calling our home phone instead of our cell phone numbers we gave them, then they gave him a locksmith number and told him he would have to call from the pay phone outside, one small problem, he didn't have any money or change with him when he locked himself out. Someone finally gave him some change to call, locksmith came, took only a couple of minutes, $50 and done. We still laugh about it, I repaid him the $50. Funny part, we went for a walk that evening and there was the locksmith at another site trying to unlock a car.
