Hi r/locksmith. I am trying to replace a deadbolt on my rear door of my garage. I live very close to the ocean and the metal just gets destroyed on “finished” hardware. It has a basic residential Schlage deadbolt that I lost the key to, but it’s not worth re-keying because the rest of the hardware is disintegrating. So, I bought a Grade 2 commercial deadbolt thinking “it’s stainless steel – that should last longer than this cheap residential one!”
The bore hole for the deadbolt is like… 1/2” bigger than my existing hole. So I returned it, as I’m not messing with trying to widen that hole. I now found a Schlage B60 CSK V 626 online that claims to fit all pre-drilled doors, but no where that I can find says anything about bore hole size… or if commercial deadbolts have different “standard” hole sizes than residential deadbolts.
Please help me pick the correct deadbolt!
EDIT: I ended up taking the route suggested by u/Odd-dog88. Just ordered the Irwin door kit and a Tell stainless steel commercial Grade 2 deadbolt. I don’t lose the security benefit of that shroud being removed from the deadbolt, I get something corrosion resistant, and my door is brought up to standard so this is easier in the future.
It turns out that the door was originally bored for a Baldwin deadbolt, and somewhere over the years someone changed it to the Schlage with the shroud removed.
EDIT2: By the way, you guys are a great and really helpful community!
