I have a very old front door with a moderately old Sears deadbolt which I would like to replace.
There are no visible screws or obvious screw holes.
I am able to gently rotate the outer ring on both sides of the door but it does not appear to actually loosen and there are no obvious notches for inserting a screwdriver to pop off a trim plate.
I would prefer to remove it without marring or damaging either the lock or the door as I want to reuse it in a future project. Therefore I've been reluctant to just stick a screwdriver in and start prying.
How do I remove this deadbolt?
