    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

    Factory Latch Weaknesses

    • • Simple latch mechanism easily pried
    • • No deadbolt-style throw
    • • Often worn after years of use
    • • Visible from outside through glass

    Track & Frame Issues

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