SUMMIT DOORWARE Sliding Patio Door Lock for Enhanced Home Security | Sliding Door Locks with 2 Keys | Lock for Sliding Glass Door | Door Security | Keep Your Family Safe and Secure

This lock is exactly what I was hoping for. I wasn’t sure how it would work exactly but after my husband got it all installed, it’s amazing. The lock attaches to the sliding door and the peg slides up into a hole that is drilled in the top of the frame. There are no issues opening or sliding the door with this installed and when it’s locked with the key, there is no way to open it. You can lock with or without a key, but without a key, it’s not child proof. We bought this to keep my autistic almost ten year old son inside the house and to prevent eloping. We’ve been having issues with him waking up and letting himself out in the backyard to play in the very early morning hours while the rest of the family is still sleeping. Today he woke up, came downstairs and was very upset to see the new lock. He tried everything he could to get it open. You can see he’s already scraped and scratched it up trying to get it unlocked or ripped off, however it is truly child proof. It may not be pretty and in perfect condition anymore, but I have peace of mind knowing it’s great quality and strong. The tried so hard to get out this morning and nothing worked. This lock will keep my child safe.

Watch the videos that come with this item. People give it five stars and so do I. Easy to install and they work great. Nobody is going to break in using these. It was a little hard to drill through the door wall.

I’ve used this brand multiple times and it never disappoints. The installation is quick and straightforward—no unnecessary hassle. The lock feels sturdy and secure, and the key function works smoothly every time. Definitely my go-to choice for sliding patio doors. I only tried a different brand once because of shipping delays, but I’ll stick with this one whenever possible.

Good quality and gives all the screws to install!

Easy to install and very strong. Worth in money

Great product - works great

Gives me a bit more peace of mind when I'm not at home. Easy to attach, I'm using it down low for a few reasons, my door is 1973 era so it was easier to mount on bottom so that the bolt goes through the solid sill plate. I don't mind having to set one more lock before leaving. The bolt can be pulled out if you want after unlocking, just twist it as you pull upwards or downwards if you mount yours above at top of door. Easy to use, hardware is solid build, worth it in my opinion.

This is a nice design but… DO NOT put any torque on the screws they are the cheapest possible and will snap off nothing flat. This will make mounting a nightmare…. Use hardware from a hardware store…. A little thicker housing would make it so the drill would not have to be at an angle to drill into the frame. This would not cost much but make a better fit. All drills too big to drill that close to the frame. Great idea - a few design flaws.
