Peter, I have the same locking mechanism as well. I also got locked inside the unit on one of our first trips when the locking mechanism cylinder broke and got stuck. Had to literally take the door apart from the inside to get out. Wife got scared at that point. Bauer had a problem with a shipment of locks but I think that has been remedied. One problem I continue to have which I thought was low batteries was not. I measured the voltage on the batteries and they were fine. What was happening is somehow, the unit was losing its code to unlock. I program my own code in. What I found out was I could re-program the unit, and it works fine, until the next time. Does not happen often as we camp every month. Maybe every 6 months or so this would happen. I just reprogram on the spot, and move on. I, like you, love the unit when it works. I do keep a key on me, just in case. Have not gotten locked in any more.
