One、Lubricate lock pins with graphite or lubricant?？
Graphite powder. The reason why graphite powder cannot be used for lubrication is due to the following:
1、Lubricating oil has an adsorption property and easily attracts dust, which can cause the button to malfunction and the lock mechanism to fail.
2、Opening locks may contaminate hands and clothing.
3. If the lock mechanism contains plastic components (including rubber), it can corrode the plastic, rendering the key unusable.
What are the methods for lubricating anti-theft door locks?
1、Alternatively, you can purchase a specialized graphite powder to lubricate, or gently scrape graphite powder from a pencil with a small knife.
2. Insert pencil lead powder into all visible gaps of the door lock. To prevent the powder from falling, place a piece of paper underneath.
3. For areas that come into contact with door locks and experience friction, apply pencil lead powder as well. In general, any area that experiences friction and contact should be treated with pencil lead powder.
4. Then, operate the door lock several times to ensure that the pencil lead powder is evenly and firmly attached to these areas. This will result in a very smooth surface.
