I have a cabin built about 1930. The front door has a deadbolt - with a key on both the outside and the inside. The name of the lock is HARLOC I want to replace it but it's not at all clear to me how to remove the old lock. On the inside there are two places which I imagine might be lead plugs that have been installed over bolts? This is just my guess. Can anyone tell me how to take it off the door?
