I’ve heard of putting in set screws. From the inside when the door is open, but have never done that myself. I have a back door that is the same and I worry every time I leave town. I’m thinking I might have to try the set screw deal myself.
Do the deadbolts use a key from the inside? lol just funnin :)
Figuring out how to do something you have never done is what makes a good challenge.
