My window locks are suddenly hard to turn this January and I’m afraid they’ll break. Why does this happen?

In the age of the internet, numerous hacks circulate about how to fix stiff locks, especially during winter. Some suggest using household items like WD-40, graphite powder, or even cooking oil. While some of these can offer temporary relief, they may not be suitable for long-term use.

Graphite powder is often recommended because it doesn’t attract dirt and dust like oil-based lubricants can. However, it’s essential to apply it sparingly to avoid clumping. On the other hand, using products like cooking oil can lead to gumming up the mechanism over time, exacerbating the problem.

To assess whether your window lock is at risk of breaking, start by gently testing its operation without forcing it. If it feels unusually stiff, check for visible signs of corrosion or misalignment. Listen for any unusual sounds when turning the lock, such as grinding or squeaking.

Another test is to observe whether the lock becomes stiffer at certain times of the day, which could indicate temperature-related issues. These simple checks can help you determine whether professional intervention is necessary.

If your lock is stiff, start by cleaning it with a soft brush to remove dirt and debris. Apply a small amount of graphite powder or a dry lubricant to the mechanism, ensuring that it penetrates the moving parts.

Gently work the lock back and forth to distribute the lubricant evenly. Avoid using excessive force, as this can cause damage. If the lock remains stiff, consider adjusting the alignment of the window frame to relieve pressure on the lock.

If DIY methods fail to improve the lock’s functionality, or if you notice significant wear or damage, it’s time to call a professional locksmith. A pro can assess the lock’s condition and determine whether it needs repair or replacement.

Additionally, if your windows are part of an older home, a locksmith may offer insights into preserving historical features while enhancing security and functionality.

To prevent window locks from becoming stiff next winter, conduct regular maintenance in the fall. Clean the locks thoroughly and apply a suitable lubricant before the cold sets in.

Consider installing weather stripping to reduce drafts and moisture buildup around windows. Regularly check the alignment of your windows and adjust as necessary to ensure smooth operation throughout the year. Preventive maintenance is key to avoiding the common pitfalls of winter weather on window locks.
