Front doors get the attention, but sliding patio doors are often the easiest way into a house. The factory latch is usually a small hook that can be lifted or pried.
Quick fixes that work
- Drop a cut dowel or a security bar in the bottom track so the panel can't slide.
- Add anti-lift screws or blocks in the top track so the panel can't be lifted off.
- Install an auxiliary keyed lock or a foot lock at the bottom of the frame.
When to call a pro
If the latch doesn't catch, the rollers are worn or the door won't stay aligned, that's door lock repair territory. A proper lock installation on a slider makes a bigger difference than any gadget. Pair it with a solid deadbolt on your main doors and rekeyed locks after you move in.
