If you have old doors in your home, chances are they’re filled with mortise locks. We often just use them as a latch, like a modern tube latch, but the intent behind them was that you could lock the individual doors of your home, usually with a skeleton key.
Most folks want a locking door — in a bedroom or bathroom — but would rather do without keys. There are mortise locks with a thumbturn hub rather than a key, but the antique thumbturn mortises are incredibly uncommon.
Most customers swap out their old mortise cases, but one customer in our Portland store had an… innovative solution.
They found a skeleton key that fit their lock, then careful modified an old thumbturn. That’ll do it!
