Sliding Glass Door Child Lock - OKEFAN 4 Pack Baby Safety Slide Window Locks for Kids Proof Patio Closet Doors No Drilling Tools Needed (Blue)

Works great for the back sliding door.

This worked for me immediately. We have multiple sliding glass doors in our home. Our two year old quickly figured out how to open and unlock them, which is an issue. One of my biggest fears was the doors being opened at night without my knowing and an accident occurring. These instantly took that worry away from me. I was very skeptical about these working because so many times something claims to be childproof then isn’t. However these are strong enough that my two year old can’t open the door when In use. I will say that I don’t think these are suitable for older children that can reach via chair or other means. They are very easy to close, and aren’t difficult to figure out. If my toddler could reach, he would be able to close the latch and open the door. So keep that in mind. BUT for us, and for now, these work great.

This is a must have if you have kids and sliding doors! I would recommend putting it all the way to the top. I didn’t do that on the first one I installed and then I could get it off to move it. They do prevent the door from opening and they have held up great.

Great product for the price. Its easy to use and works well. I finally have a peace of mind now that my toddler cant open the door on his own.

I bought this to add more security on my sliding back door and also prevent my toddler to open and run out but still keep the air flowing through the door. The white plastic with blue accent locks looks pleasant. The surface is rugged with strong 3M adhesive on the other side. It’s easy to install, just peel and stick and it sticks good. It wasn’t skinny enough for my glass door to run over it. The door still make a contact over the lock, but it not too bad. I installed 2 locks on the glass, 1 ft from top and 1 ft from bottom to spread the impact. The lock and unlock is pretty simple and straightforward. I like it. I have 2 more to install it later if needed.
