Husband went out to 17' SD that has been sitting up for some time, uncovered and exposed to weather. Cannot get lock to work. Broke off one key in it, so he went to hardware store and had more made. Sprayed with WD 40 yesterday. Factory not calling him back. Saw a similar problem in a post here from 2013 for a different lock. The one we have is kind of square on the outside and you pull the latch out to open it.
He is hesitant to drill it out without knowing what he is getting into or what size bit to use.
We have a trip planned with friends next weekend. Husband is saying a lot of words he learned in the Navy and some he taught the other sailors.
