Locks take a real beating in cold weather, contraction, moisture freezing inside the cylinder, and thickened lubricant all conspire against smooth operation. Here's how to stay ahead of it.
Use the Right Lubricant
Graphite powder or a silicone-based lubricant works well in cold weather. Avoid WD-40 as a long-term lock lubricant, it attracts dirt and can gum up in low temperatures, making things worse over time.
If a Lock Freezes
Don't force the key, that's how keys snap. Gently warm the key with a lighter (briefly, not hot enough to burn yourself) and insert it slowly, or use a de-icer product made specifically for locks.
Watch for Metal Contraction
Cold causes metal components to contract slightly, which can make an already slightly-worn lock feel noticeably stiffer in winter. If this is new this season, see key won't turn in lock for the full troubleshooting list.
Protect Exterior Locks From Direct Moisture
A simple weatherproof cover over an exterior lock cylinder reduces how much moisture and ice can accumulate directly on the mechanism.
Do a Fall Check-Up
Before winter hits, a quick inspection catches wear that the cold will only make worse. See signs your lock needs replacement.
