Door locks and hardware are critical for security and function. They work hard, exposed to temperature changes and constant use. Regular maintenance ensures they operate smoothly, function reliably, and last for years. Here’s what every homeowner should know.
Why Maintain Locks and Hardware
- Security: Working locks are essential for safety
- Reliability: Prevent lock failures when needed most
- Extends lifespan: Simple maintenance adds years
- Saves money: Maintenance is cheaper than replacement
- Smooth operation: Eliminates sticking and binding
- Increases property value: Well-maintained security increases value

Lubricants for Locks and Hardware
