Oiling a door lock is a simple process that can improve its function. Here's how:
-
Identify the Lock Type: Pin tumbler, wafer tumbler, or lever tumbler locks require slightly different approaches. However, the basic principle remains the same.
-
Gather Your Supplies: You'll need a lubricant specifically designed for locks (graphite powder, silicone-based lubricant, or Teflon-based lubricant are good choices). Avoid using WD-40 as a long-term solution; it can attract dust and eventually gum up the lock. You may also want a straw applicator for precision.
-
Apply the Lubricant:
-
Spray Lubricant: If using a spray lubricant, attach the straw applicator to the nozzle. Insert the straw into the keyway as far as it will go. Give a short burst of lubricant. Line up the arrow on your spray head with the dot on the can for proper direction.
-
Graphite Powder: For graphite, puff a small amount directly into the keyway.
-
-
Work the Lock: Insert your key and turn the lock several times. This will distribute the lubricant throughout the mechanism. Remove the key and wipe off any excess lubricant.
-
Repeat if Necessary: If the lock is still stiff, repeat steps 3 and 4. However, avoid over-lubricating, as this can also attract dirt and debris.
-
Address Other Parts (Optional): If the strike plate is misaligned, you can also lubricate the bolt where it contacts the strike plate.
Important Considerations:
- Type of Lubricant: Using the correct lubricant is crucial. Avoid oil-based lubricants like WD-40 as they can attract dust and grime over time. Graphite powder, silicone, or Teflon-based lubricants are specifically designed for locks and provide long-lasting lubrication without attracting debris.
- Keyway Obstructions: If the lock is particularly dirty, consider using a lock pick set to gently remove any obstructions before lubricating.
- Professional Help: If the lock is still not functioning properly after lubrication, it may be damaged or require professional locksmith service.
