Why Sliding Doors Are a Security Vulnerability
Sliding glass doors are the second most common entry point for residential burglaries. Most factory latches can be lifted off their tracks or forced open in seconds. In Austin, where backyards provide concealment, sliding doors are an attractive target.
7 Ways to Secure Your Sliding Glass Door
1. Secondary Lock or Double-Bolt ($30–$60)
Adds a second point of engagement that’s much harder to force.
2. Security Bar in the Track ($15–$40)
A cut-to-length metal bar in the floor track prevents the door from being slid open even if the latch is defeated. Do this today.
3. Anti-Lift Pins ($20–$50)
Drilling pins through the door frame and into the upper track prevents the door from being lifted out.
4. Keyed Sliding Door Lock ($40–$80 installed)
Replaces the factory latch with a keyed mechanism, requiring a key to open from outside.
5. Security Film on Glass ($3–$8 per sq ft)
Holds shattered glass in place, making quick entry much harder. Also protects against Austin’s severe thunderstorms.
6. Door Sensor Alarm ($20–$50)
Alerts you when the door is opened. Creates an audible deterrent.
7. Motion-Sensor Lighting Outside ($40–$120 installed)
Eliminates the concealment that makes sliding doors attractive targets.
