Improved Childproof Door Lever Lock (3 Pack) Prevents Toddlers from Opening Doors. Easy One Hand Operation for Adults. Durable ABS with 3M Adhesive Backing. Simple Install, No Tools Needed

No kids in my household, but it did stop my demon fur child from sneaking into my room. It is the hardest working little plastic I have ever bought. Just buy it! You won’t regret it. Make sure you place it exactly where you want it and it may or may not rip out paint from your door…

I was concerned but now I’m confident these were a great buy

Highly recommend for safety.

Super useful - despite being non-human apparently my cats taught themselves how to open doors and I got tired of coming home to everything being open and mildly ransacked. Theyre easy to work and can be opened with one hand while Im completing my morning routine. I am in an apartment so being able to take them off will be important once I leave, but well see. NOTE: a friend locked themselves in the bathroom by accidentally putting the bottom lever back up before going in and closing the door. Unless you know that your doorknob doesnt move upon opening/closing make sure to keep the lever down!!

Great adhesion, super easy to install and easy to use!!! We were having to lock every single door in our house to keep our 2 year old out of bedrooms. It was a hassle to find things to turn the lock back open. These are super convenient and doesn’t look tacky on doors.

I needed something to prevent my 2 year old from opening doors in the house. These were perfect. Easy to put on and easy to get in and out. The only flaw is that if Im in my bedroom or bathroom, I can get locked in there if someone put the baby lock up. My 4 and 6 year old know how to use it so they like to be silly and lock whoever in a room.

Beware … the description says the 3M VHB adhesive tape is removable but I researched it on the 3M company website and it is only removable with special tools and most likely will damage the surface it was attached to. I’m going to return the product.

My suggestion, as others have mentioned, is to put these bad boys on upside-down so that the part that does not move is below the handle. Our little one is juuuust tall enough to pull down on the handles. This stops him without us having to fully lock the handle in place. We just turn the handle up. Only sort of bad thing is the handle just barely fits past the lock mechanism when it is unlocked. So if you have fancy door handles, measure those bad boys for clearance. Very happy with them and will be ordering more. They do what they say they do.

I teach an autism class and I have a student that is a runner. We got these locks last school year and the student was not able to open the door! I wanted to make sure that I had extras in case the stickiness became lax. The student still isn’t able to open the locks so job well done!

Yup, I got a salon cat that likes to eat all the food on the floor. We are talking food for SALE! So, this really helps. I found that the commercial handles I have will open from the other side even tho one of these items is on the other side. The handle that is still flexing allows us to activate the white child proof on the outside of the door and then close it going into the room you dont want the animal to access and not be able to go in and out of areas you want to keep on lock down. Check your knobs before applying the sticker, I found I had to move a couple to the opposite side of the door. Just locking the inside one allowed the outside handle with no safety on it to still be opened. Who knew! Now you know. Worked great. The sticky is seriously strong. Dont push it down too hard if you might have to move it due to mistake.
