I was at a launch ramp last year and got out of my coach to prep the boat for launch and the wind blew my door closed and locked me out, my drivers window was open so I was able to climb through it, when I got home I took apart the latch to see if anything broke, all was good and turns out the dead bolt was what was locking and the reason is the mounting screws on the inside for the entire latch assembly were just a little loose and lets the dead bolt move with a the impact of the door closing hard, after the reassembly an with the screws tight the dead bolt no longer moves when the door closes, I also keep a set of keys outside now in a safe place
