Combination Bolt gate Lock (OWACH AL-971) Combi Bolt Latch,Sliding Barrel Bolt Lock, Stainless Steel Sliding Bolt (White)

Our 5.5 year old son figures out every type of lock but struggles with memorizing numbers, something we are actually extremely thankful for right now. We've used all the recommended locks for alzheimer's patients but he's figured all of them out. He can bust off any child proofing so those are out too. We were getting ready to drop $1,500+ on three 2 way coded locks for exterior doors when someone recommended these combo slide locks. They're perfect! Our son hasn't figured them out and it's been a couple of months now. This is important since he is nonverbal, his gps tracker doesn't always work, and he is a repeat wanderer. These keep him safe and allow us to use the bathroom or shower or even just sleep without keeping an eye and an ear out for an exterior door opening.Now for the lock itself. Seems well built. We had to adjust it a bit to fit our 1990's doors and mukti-level door frames. Some shims and nuts (what we had on hand) were all that were needed to get it lined up. The bolt slides fairly easily, it sticks a bit, which makes it loud when opening and closing it. Not a problem for us, as it would buy us time to hear if our son managed to figure it out at some point.As others may have mentioned, in the open position, it displays the unlocking code and the numbers cannot be moved. Keep this in mind if it's something you need to remain a secret. Once you slide the bolt closed, then you can spin the numbers and you have to do this otherwise it can be slid open again without entering the code.The other lock in the photo is the Door Guardian, recommended for alzheimer's patients, and it worked great here before he figured out how to open it.

Wish zero stars was an option! I paid to have this installed on an iron garden gate, it broke before the contractor even left, paid him to remove it. The slide bolt pulls right through and opens, even when “ locked”. I now have holes drilled in the iron gate. The company that sells the lock never responded to my complaint, or to amazon’s request for them to contact me. It is a huge piece of junk! It was thrown in the trash!

great quality, very heavy duty, but wish the screw holes could be engineered inside. Anyone can unscrew these if they wanted.

Looks really nice. Easy to unlock. But also way too easy to accidentally change the combo. One way screws do their job, so will be some damage to your door if you need to replace the lock.

I wish I had paid more attention to the reviews. When the lock is open you cannot move the dials ... so there is no way to keep the combo secret unless you want to change it every time you open the lock. No bueno. I am going to return it.

A great solution when you have to keep someone in the house, not just keep intruders out. My wife with dementia wanders and would try to get out but now, problem solved!

It seems solid and big but in my opinion has a critical defect, which is that the combination cannot be scrambled once the bolt is open. Anyone who notes the numbers when the bolt is open will know the combination. Or, you will have to set and memorize a new combination each time you plan to close the bolt....

Installation of this was relatively easy, but you are using security screws that aren’t easy to screw in, and can’t be unscrewed. This makes sense, except when the lock malfunctions. We installed this to lock an interior closet. It locked it alright, but then the code didn’t work to unlock it. It worked the first couple times when we tested, but then failed to open once it actually was in use. The only way to remove was to cut the lock and receiver off with a reciprocating saw, causing a lot of cleanup and fixing of the door. Beware!
