So new camping trip, new opportunity. Before we leave the house we normally lock the camper (not sure why we don't leave anything in there to steal, although I wish someone would steal the tv... then I can upgrade to one of them new flat tvs). But none the less we stick a key in the upper lock and it doesn't turn, try a different key and the same thing, and third and final key also didn't work. It appears like the keys are not going in all the way, does anyone know how I could possibly fix this? I pulled the handle and lock mechanism off and that didn't solve anything. Luckily the 23b has a dead bolt that still works. Thanks in advance.
