Most homeowners focus on door locks — but windows are the second most common burglar entry point. Standard window latches offer minimal resistance. Here's how to turn every window into a genuine security barrier.
Factory window latches are typically simple zinc or plastic mechanisms designed for convenience, not security. A firm push, a bit of vibration, or a pry tool can defeat most in seconds. Never rely solely on the manufacturer latch.
A window pin lock involves drilling a downward-angled hole through the inner sash into the outer sash and inserting a steel pin or bolt. The window cannot be opened even if the latch is defeated. Inexpensive, effective, and requires no electrical components.
For high-risk windows (ground floor, hidden from street), keyed locks provide an additional layer. They replace or supplement the standard latch and require a key to open from either side. The tradeoff is inconvenience during emergencies — always keep a key nearby.
Window security film doesn't prevent breaking, but it holds shattered glass in place for 60+ seconds — enough to deter smash-and-grab entry. Applied like tinted window film, it's invisible from outside and effective on any glass.
Magnetic contact sensors trigger an alert the moment a window opens. Glass break sensors detect the specific sound frequency of breaking glass and trigger an alarm before entry is complete. Both integrate with most home security systems.
