How should I lubricate the Kovix Locks?

These are a few tips that will help you keep your Kovix locks working efficiently:

What to lubricate:
The cylinder: when keys are hard to turn. Spray lubrication into the cylinder.
Actuator and Driver, Locking lever or ball bearings: lubricate when the shackle is hard to release. Spray the inside of the shackle.

When to lubricate:
Annual cleaning is recommended. In very dusty or corrosive environments clean every three months. Lubrication frequency will depend on the environment and usage.

How to lubricate:
We suggest the best lubricants are dry lubricants such as PTFE.
Please ensure you NEVER use oily lubricants or graphite as Oil attracts dust and eventually gums up the lock. Oil and graphite can also interfere with the movement of the pins in the locking mechanism.
