I am camping with our 303. Yesterday locking doors and all of a sudden key came out and deadbolt slot was at 9 0'clock position. Deadbolt is in lock position. Tried to put key back in but would not go all the way in. All my windows were locked. In my storage compartment I had my cordless drill and drill bits. I drilled the middle of the deadbolt cylinder out. Then I put a screwdriver in the middle of the hollow cylinder slot and was able to turn the deadbolt to the unlock position. What a big relief that was! Sure glad I had the cordless drill and bits in my underneath compartment! I camp with a well stocked tool box. Sent Dean in customer service an email and he is sending me a new lock set mechanism. Great Service GD and Dean!
