Keyed Entry Door Deadbolt with One Keyed Side and Twist-Knob Interior, 2-Way Adjustable Latch, Fits Standard Doors, Oil Rubbed Bronze – Design House, 750869

Great for use as night bolt. Give wife peace of mind at night. Worth it! Easy to install if your handy.

As described.

I prefer the Kwikset style of hardware for attaching keyless deadbolts, and they do a good job here of replicating it. Unfortunately they are a bit more expensive, and slightly lower quality then Kwikset - however if you need Aged Bronze / 11P finish this is a good option, as Kwikset seems to have discontinued the finish for Keyless deadbolts in 11P. The product could be improved significantly by providing a convertible 6-way lock bolt that allows for Drive-in functionality. It would be a 5 star product then.

Needed it for the rental. Great lock one sided

I was putting a door in for somebody and he requested a second deadbolt found this and it worked out great cuz you cannot see where it is on the other side of the door

I purchased three of these to add additional security to three french doors that open out onto my pool deck. The doors were already secured by three point locking systems but these were all operated by the main door handles - which are now in reach of younger members of our family. I mounted these new deadbolts vertically at the top of the opening door so only adults can reach them. The other advantage of mounting them vertically was that they engage with the frame of the door rather than the oposing opening door so they add yet another level of strength/security.I used an IRWIN deadbolt jig (from ACE - sorry Amazon) to cut the holes. That was the only awkard part. Because the single sided deadbolt can't screw into an outside component it has a plastic bridge that crosses from one side of the main hole to the other. I didn't think this was explained well in the instructions and I'm probably not explaining it well now either! Anyway, that requires you to drill the main deadbolt channel through the back of the main hole (where the handle mounts) and the IRWIN 1" hole bit was not long enough for that. I used a 1" spade wood bit to make the addtional hole. The mounting screws that came with the deadbolt were not very long so I replaced those with longer screws for addtional strength.Despite the deadbolt saying it has to be mounted horizontally (or at least it says 'UP' on the 'top' of the deadbolt) it's working fine vertically and has a postive 'latch' that resists opening by shaking the door. I'm happy with my purchase.

The single sided version does not have a blank for the other side of the door and no suggestion on how to cover that hole. Trust the picture. I just figured they were emphasizing the single sided aspect of this product, but it shows no cover for the hole you have to drill into your door. And there is none. YIKES! I ended up using it, but it is not easy to drill only partially through with a decent hole saw. I had to remove the center bit so it wouldn't poke through. Very strange installation... not standard at all. As you can see by the picture, even they get it wrong, showing the hole going all the way through. You get what you pay for. It will work for our situation.

A very private lock can only be opened from the inside, providing a little more security to the doors of your villa.
