Safety padlocks come in many styles, with innovative and unique designs, decorative features, and added security functions. But when it comes to maintaining them, many people don’t really know how. In fact, keeping a padlock in good condition is simple—just follow a few basic maintenance steps to ensure long-term reliable use.
1. Keep the lock cylinder lubricated
The cylinder’s drive system should be regularly lubricated so the mechanism works smoothly and the lock lasts longer. It’s recommended to check the lock every six months. In particular, check whether the screws are loose—if they are, tighten them immediately.
2. Maintain the lock cylinder every six months
Even if the lock doesn’t feel stiff or stuck, the cylinder still requires routine care. A common method is to place pencil shavings or powdered graphite into the key slot, then insert and remove the key several times to distribute it evenly. This helps the key turn smoothly. However, do not use oil, as vegetable oils or similar substances can cause the pins to stick.
3. Follow installation instructions carefully
When installing the lock, always refer to the manufacturer’s instructions. Pay close attention to the correct installation distance, applicable scenarios, and operating method to ensure proper use.
4. Keep the lock core clean
Prevent dust and debris from entering the cylinder, as this can cause stiffness or failure to open. If the key feels rough when turning, apply gasoline, kerosene, or anti-rust lubricant to the key slot, then insert and turn the key repeatedly to restore smooth operation.
