Maintenance
Proper maintenance will extend the life and functionality of your padlock.

- Lubrication: If the key mechanism becomes stiff, apply a small amount of graphite powder or a specialized lock lubricant into the keyhole. Do not use oil-based lubricants as they can attract dirt and cause clogging.
- Key Care: Store keys safely and avoid bending or damaging them. Do not use keys for purposes other than operating the padlock.
