Sliding glass doors are a beautiful feature in Dallas homes, offering natural light and easy access to patios and backyards. Unfortunately, they're also a favorite target for burglars. The factory-installed latch locks on most sliding doors are easily defeated—often with a simple screwdriver or by lifting the door off its track.
Why Sliding Doors Are Vulnerable

- • Visible from outside through glass

- • Doors can be lifted off tracks
- • Old frames may be loose in walls
- • Rollers wear out, creating gaps
- • Debris in tracks blocks proper closing
