OKEA Sliding Glass Door Lock
Childproof lock designed specifically for sliding glass doors, keeping them securely shut.

Why we feature it
A sliding glass door is often the only barrier between a toddler and an unfenced pool or a busy backyard. Factory thumb-latches on sliders are usually within toddler reach by 18 months. A secondary lock mounted high resets the access point above their reach line.
Installation notes
Mount above 60 inches on the fixed frame. The bracket sits flush - clean the aluminum or vinyl track frame with alcohol first. Test the door's sliding action after install; some adhesive blocks shift slightly under load and need a re-stick.
Renter-friendly?
Yes. Adhesive mount on most models, no drilling into the door frame. Removes with heat and slow peel. Don't drill into vinyl frames in a rental - it voids most replacement warranties.
Best for
Pulling-to-stand (10m) through about 5y.
Honest tradeoffs
- Adults must remember to use it every time - build a closing-up routine
- Adhesive blocks need a flat clean surface; weathered or painted frames may not hold
- Doesn't address pet doors built into the slider - those need a separate panel
- Won't stop a child from breaking the glass - this is a barrier-to-egress lock, not anti-burglary
When to consider an alternative
For homes with a pool, layer a self-closing pool gate and a door alarm on top of this lock - one product is never enough on a water-adjacent door.
