Quick answer:
- Factory slider latches are flimsy — don’t rely on them alone.
- Add a bar/dowel, a secondary pin lock, and anti-lift screws.
- A locksmith can upgrade the lock and stop the door from being lifted out.
Why Sliders Are a Weak Point
The standard latch on a sliding glass door is a small, spring-loaded catch that can often be jimmied, shimmied, or rattled loose. Worse, many sliders can be physically lifted out of the track from outside if the rollers and anti-lift aren’t set right. Burglars know this, which is why patio doors — common on Albuquerque homes — are a favorite target, especially in back yards out of view.
Layer Your Defenses
No single fix is enough; layer them:
- Bar or dowel in the track to block sliding
- Secondary pin/foot lock at the top or bottom of the door
- Anti-lift screws in the upper track so the panel can’t be lifted out
- Upgraded mortise lock to replace the weak factory latch
- Security film on the glass to slow a smash-and-reach
Don’t Forget Egress
Whatever you add, the door must still open quickly from inside in an emergency — don’t permanently screw it shut. The goal is to stop outside entry while keeping easy exit. A locksmith balances both, and can recommend the right mix for your specific door and family. This pairs with the rest of your home security checklist.

Frequently Asked Questions
Is a bar in the track enough?
It helps a lot but isn’t complete on its own — a determined intruder may still lift the door out of the track. Combine a bar with a secondary pin lock and anti-lift screws.
Can you replace the lock on a sliding glass door?
Yes. We replace worn slider mortise locks and add secondary locks and anti-lift hardware so the door is genuinely secure.
Will these upgrades make it hard to get out?
No — we set them up so the door still opens quickly from inside for safe egress while blocking entry from outside.
