Probably the major point of illicit entry to residential properties in southwest Florida is through sliding glass doors. Although the heavier sliders are quite secure, the lighter sliders, which comprise perhaps ninety percent or more of sliding glass doors, are easily defeatable with nothing more than a flat-faced screwdriver. Every electrician, plumber, and lawn maintenance person in Collier county knows how to quickly gain entry through a slider when the contractor has failed to provide a key. Therefore, a secondary lock on sliding glass doors is often critical. A number of good secondary locks are available, the best of which involve only metal to metal, never metal to wallboard installation. Let A Beach Locksmith actually test out the security of your sliders, and make some recommendations for good secondary locks.
