Hi - I think I have an old screen door handle set that looks roughly like a 40-042 (first picture). I just installed a Kwikset smartlock deadbolt, and I discovered that the internal screen door handle rests on the "lock" button of the smartlock keypad (second picture).
I need to raise the screen door handle ~5/8" to clear the keypad, but that would require moving the entire handle, drilling three new holes, and exposing the original lower hole in the door.
Looking at your inventory, I wondered if I could replace it with a 40-138. The 40-138 handle is positioned a bit higher and would clear the top of the smartlock face. I would probably have to drill another center and bottom hole, but I wouldn't have to change the location of the inside and outside trim pieces, so they would cover the old holes. However, the door itself is 15/16" thick, and the 40-138 fits doors 1-1/8" to 1-3/8" thick.
What do you think? Could I make this work? Any other suggestions?
