Buying Guide: How to Choose Sliding Door Locks

Sliding Door Locks: Closing the Giant Vulnerability

Sliding glass doors are basically invitations to burglars. The factory latch is a joke, and most doors can be lifted right off the track.

Two Attack Vectors
1. Sliding force: Overwhelming the weak latch
2. Lifting out: Picking the door off its track entirely

Good security addresses BOTH.

### Solution Types

Track bars/Charlie bars:
Placed in track to block movement
- Only work when you're home
- Simple, effective, cheap

Loop locks:
- Screwed to frame and door
- Keyed for away-from-home security
- Requires drilling

Anti-lift devices:
- Screws into upper track
- Prevents lifting door out
- Often overlooked but critical

Full security bars:
- Floor-to-top bracing
- Maximum resistance
- More obtrusive

### The Complete Solution
For real security, you need:
1. Track bar OR loop lock (prevents sliding)
2. Anti-lift device (prevents removal)
3. Optionally: alarm or glass-break sensor

Frequently Asked Questions About Sliding Door Locks

Can someone just break the glass?

They can, but rarely do—breaking glass is loud and attracts attention. Most burglars prefer forcing locks quietly. For glass protection, add security film which holds shattered glass together.

Do I need both anti-slide and anti-lift?

Ideally yes. A surprising number of sliding doors can simply be lifted off the track. A track bar stops sliding but not lifting. Cover both vulnerabilities.

What about the screen door?

Screen doors offer zero security—they're just there for bugs. Never rely on a screen door lock. Secure the glass door itself.
