Window Lock Options: Keeping Intruders Out From Every Angle

The Window Security Gap

Most homeowners invest in quality door locks but neglect their windows. According to FBI crime statistics, approximately 23% of residential burglaries occur through first-floor windows. In Utah, where many homes have ground-floor windows adjacent to landscaping that provides cover, this is a significant vulnerability.

Types of Window Locks

Sash Locks (Standard)

The factory-installed crescent sash lock on most double-hung windows is designed to keep the window closed — not to resist forced entry. These can often be jiggled open without breaking the glass.

Window Pin Locks

A simple but highly effective solution: a metal pin or bolt inserted through a hole drilled through the inner frame and partway into the outer frame. Cheap, easy to install, and very effective.

Window Key Locks

Keyed window locks require a key to open from inside — preventing windows from being used as an exit route by intruders who entered elsewhere, and adding friction to any forced entry attempt.

Window Stop Locks

These prevent the window from being opened more than a few inches — allowing ventilation while preventing entry. Great for bedrooms and basements.

Window Bar Locks

For maximum security on basement or ground-floor windows, interior security bars prevent entry even if the glass is broken. Quick-release mechanisms allow emergency egress.

Window Sensors

While not a lock, window sensors that trigger your alarm if a window is opened or broken add an important electronic security layer.

Sliding Window Security

Sliding windows have the same vulnerabilities as sliding doors. Use security bars in the track and anti-lift pins to prevent removal.
