To use graphite powder in a lock, apply a small amount of the powder inside the keyhole to ease friction and improve the lock's function, especially in conditions that might affect its sensitivity.
Steps for Applying Graphite Powder to a Lock:
While the provided reference video is short, the implied method is fairly standard. Here's a more comprehensive approach, based on common practices:
-
Obtain Graphite Powder: Purchase graphite powder specifically designed for locks. This can usually be found at hardware stores. Avoid using substitutes like pencil lead shavings, as they may contain binders that can gunk up the lock mechanism over time.
-
Prepare the Lock: Ensure the lock is as clean as possible. While you're adding graphite to reduce friction, you want to ensure any existing debris isn't compacted by the graphite.
-
Apply the Graphite:
- Puffer Bottle/Tube: Many graphite powders come in small puffer bottles or tubes designed for easy application. Aim the nozzle directly into the keyhole.
- Key Application (Alternative): If you don't have a puffer, you can apply a very small amount of graphite powder to the key itself. Insert and remove the key several times to distribute the graphite within the lock cylinder. Wipe off any excess graphite from the key after each insertion.
-
Work the Lock: After applying the graphite, insert and remove the key several times, turning it in both directions to distribute the lubricant throughout the internal mechanisms. This helps to evenly coat the pins and cylinders, reducing friction.
-
Remove Excess: Wipe away any excess graphite powder that may come out of the lock. Graphite is a dry lubricant, so a very small amount is sufficient.
-
Test the Lock: Check if the key turns more smoothly. You may need to repeat the application process a couple of times if the lock is particularly stiff.
Important Considerations:
- Use Sparingly: Too much graphite can actually cause problems by attracting dirt and debris. A little goes a long way.
- Frequency: Graphite lubrication is not a frequent task. Reapply only when you notice the key becoming difficult to turn.
- Avoid Liquid Lubricants: Do not use oil-based lubricants like WD-40 in locks. These can attract dirt and eventually cause the lock to seize up. Graphite is a dry lubricant, which is much better suited for locks.
- Professional Locksmith: If the lock remains stiff or problematic after applying graphite, it may be necessary to consult a professional locksmith.
