What to Do When a Window Won’t Lock

Check the lock, ensuring it is properly engaged, and nothing prevents it from locking.

Windows that won’t lock are frustrating and can leave a homeowner feeling vulnerable and exposed. It’s essential to determine the cause quickly. Homeowners can resolve the matter themselves before calling a locksmith for assistance.

This article will discuss why a window might not lock and some easy solutions and preventative measures.

Check for ice or debris

Check to ensure the lock is not frozen by ice or debris if it's winter. Thaw it with a hair dryer or heat gun if it is frozen. If the lock is still not working, it may need replacing. During other times of the year, ensure no debris is blocking the locking mechanism. Clean if necessary.

Check the lock

Check the lock, ensuring it is properly engaged, and nothing prevents it from locking. Lubricating the lock may help.

Check the frame

Check that the window is sitting square in its frame. If it is, check that the frame is not warped. Additionally, check to see if the frame is loose; tightening it with a screwdriver may resolve the problem.

Check the weatherstripping

Check the weatherstripping to ensure it is in good condition and is properly sealing the window. If it’s damaged, consider replacing it.

Adjust the window

Adjusting the window by lifting it slightly or pushing it down gently so that the lock engages properly is an easy solution.

Call a professional

If none of these things work, it’s time to call a professional. A qualified locksmith or window repair specialist can diagnose the problem and recommend the best action. Sometimes, the issue may be with the frame or hinges, requiring more extensive repairs. Don’t hesitate to call a professional for help with locking windows. They can sort out what’s causing the issue and offer a workable solution.

How to prevent future window lock issues

One of the best ways to prevent future window lock issues is to regularly maintain and clean the windows. Maintenance allows homeowners to inspect the windows to ensure that the locking mechanism is not damaged or obstructed in any way. Take action if problems are detected.
