I think that we’ve finally gotten to the end of the door saga. We bought more new door hardware yesterday, this one is a very nice Baldwin. Scott installed it last night, in under an hour. It doesn’t look much different from the other hardware, but so far, things are going much, much better.
Namely, the door reliably opens, we haven’t gotten a key stuck, and we can open the door from the inside. So I’m chalking this up as a win.
