Doors – Opposite of double key deadbolt

doorslock

I'm looking for a deadbolt that has the handle/knob on both sides. Basically the opposite of a double-key deadbolt. The purpose is to put it on our basement door out of reach from the kids. An adult can lock/unlock the door from either side and would never get totally locked on either side, without needing a key.

Any ideas?

I was able to accomplish your solution to this problem as you rather originally imagined it, a double sided non-keyed thumb-turn deadbolt lock – I searched for a while but was not able to find such a thing standard made - of course probably the simplest fastest solution is the prior suggestion of a deadbolt lock with thumbturn on one side and key locking on the other side and just leave the key in it all the time (with a bunch of spare keys available lol) – those ARE standard made – in my house I have a swinging door that often needs to be locked to keep a dog on one side of it but easily unlocked on both sides for human passage - in my solution, I bought two standard one-side thumbturm deadbolts and was able to kludge them together through the door without too much trouble. Had to drill the big round hole through the door of course and also for the deadbolt latch itself into the door – main thing was buying two long proper fitting machine screws with nuts that went all the way through the door and joined the two opposite side thumbturn plates together.

Anybody who tries the same can just buy the two locks and study the situation and solve their way through it OK in half a day with otherwise proper standard tools and hole saw drill bits. I also installed a door pull handle on each side to facilitate operating the door and also exactly positioning it for latching.Those attach with simple wood screws.
