How to Lubricate Sesame Combination Lock

Combination locks, like the iconic “Sesame” style locks, are a convenient way to secure lockers, boxes, cabinets, bags, and other belongings while avoiding the need to keep track of keys. However, like any mechanical device, combination locks can malfunction over time if not properly maintained. Lubricating a combination lock helps the internal mechanisms turn smoothly, allowing you to easily open it using the correct combination. With just a few household items and tools, lubricating a combination lock is a quick and easy process.

Why Lubricate a Combination Lock?

Lubricating a combination lock provides several important benefits:

  • Prevents sticking – Lubricant reduces friction so the dial and internal parts turn freely without sticking or jamming. This makes it easier to open the lock.
  • Enables smooth operation – A lubricated lock dial rotates effortlessly to align the internal tumblers to open the lock. This prevents the frustration of the dial catching or binding while turning.
  • Reduces wear and tear – Lubrication minimizes metal-on-metal abrasion inside the lock. This extends the operating life of the internal mechanisms.
  • Protects against rust – Lock lubricant blocks moisture from reaching bare metal surfaces inside the lock, preventing corrosion and rust formation.
  • Cleans out dirt and debris – Application of the lubricant cleans grit and grime out of the lock interior that could interfere with proper functioning.

Regularly lubricating a combination lock every 3-6 months ensures it continues working reliably for many years. It takes just a few minutes but makes a big difference in preventing malfunctions.

How to Lubricate a Sesame Combination Lock

Lubricating a combination lock is a simple process that requires only basic household tools and supplies. Here are the step-by-step instructions:

Step 1: Clean the Combination Lock

Before lubricating, use a dry cloth to thoroughly wipe down the exterior of the combination lock to remove any dirt, dust, debris, grease or existing lubricant. Make sure the lock dial moves freely and does not stick. If needed, use a small brush or cotton swab dipped in rubbing alcohol to scrub the dial and front face of the lock body clean.

Step 2: Apply Graphite Powder Liberally

Once the lock is clean, use a powdered graphite lubricant to lubricate the lock interior. Graphite powder can be purchased from hardware stores and locksmith suppliers. Apply the graphite powder liberally over the entire dial and into the keyhole on the bottom or side of the lock body.

Step 3: Work the Lubricant Into the Lock

After applying the graphite powder, turn the dial slowly several complete revolutions clockwise and counter-clockwise. This works the dry lubricant into the internal mechanisms of the lock. The turning action distributes the graphite and coats all the moving parts. Be patient and turn the dial enough rotations to feel it moving smoothly.

Step 4: Reapply Lubricant Periodically

The combination lock should now operate easily with the dial rotating smoothly to open the lock. Over time, the graphite powder will wear off the internal parts. Regularly reapply dry graphite lubricant every 3-6 months or whenever the dial motion becomes stiff or gritty feeling.

Here are some tips for effectively lubricating combination locks:

  • Only use powdered graphite as a lock lubricant. Do not use WD-40, oil, or other liquid lubricants which will attract dirt and gum up the mechanisms.
  • Focus application on the dial and keyhole to reach the internal moving parts. Avoid getting graphite powder on the outer lock body which can make a mess.
  • Turn the dial fully when working in lubricant to distribute it evenly. The internal wheels and levers need even coverage.
  • Reapply dry lubricant periodically before locks seize up. Liquid sprays wash away quickly. Dry graphite powder has longer lasting lubrication.
  • If a lock is stuck and won’t open, don’t force it. Aggressive twisting can damage the internal parts. Thoroughly clean and lubricate stiff locks.
  • Ensure combination locks stay clean between lubrication. Keep dirt, sand and liquids out of the mechanisms which can accelerate wear.

Proper lubrication keeps combination locks working smoothly for years of trouble-free security. Follow this simple graphite powder lubrication process periodically to maintain easy, reliable function.

Dos and Don’ts of Lubricating Combination Locks

Dos

  • Use only powdered graphite as a dry lubricant
  • Apply lubricant liberally to the dial and keyhole
  • Turn the dial fully when working in the lubricant
  • Lubricate regularly every 3-6 months
  • Keep lock exterior and interior clean

Don’ts

  • Use WD-40, oil, grease or other liquid lubricants
  • Force the dial if a lock is seized up
  • Allow locks to get wet or attract dirt inside
  • Over-apply lubricant to the point drips out
  • Use excessive force when turning a stiff dial

Frequently Asked Questions

How often should you lubricate a combination lock?

Combination locks should be lubricated every 3-6 months with dry graphite powder depending on usage levels. Locks used daily or exposed to outdoor elements may need lubrication more frequently. Try to lubricate locks routinely before they bind or malfunction.

Can you use WD-40 to lubricate a combination lock?

No, WD-40 or other liquid lubricant sprays should not be used in combination locks. The liquid can attract dirt and gunk up the precision internal mechanisms. Only use dry powdered graphite for effective combination lock lubrication.

What happens if you don’t lubricate a combination lock?

Without periodic lubrication, a combination lock can become stiff and difficult to open. The lack of lubrication allows metal surfaces to rub and scrape together leading to faster wear of the internal parts. Prolonged lack of lubricant can result in complete seizing and failure of the lock.

What if the combination lock dial is not moving after lubricating?

If the dial remains stuck and does not rotate freely after thorough cleaning and application of graphite powder, the lock may require internal repair or replacement. Do not force a seized dial as this can cause internal damage. Try contacting the lock manufacturer or a professional locksmith.

Can you use lubricant sprays to lubricate a combination lock?

No, lubricant sprays should be avoided as they can introduce too much liquid into the precision lock interior. Stick with dry graphite powder only for lubricating combination locks. Some lock specific dry lubricant sprays are exceptions that mimic graphite powder application.

How do you re-secure a lubricated combination lock?

After lubricating a combination lock, simply spin the dial several times, then set the lock to the combination code to relock it. This scrambles the wheels from the lubrication process and resets them to lock at the chosen combination. Test opening it with the code a few times to ensure proper function.

Final Thoughts

Lubricating a combination lock properly is easy with some basic guidance. The key steps include cleaning with a cloth, applying dry graphite powder generously both inside and out, working the lubricant in by turning the dial, and repeating the lubrication every 3-6 months.

Following this simple process keeps combination locks operating smoothly for years of reliability. Lubrication prevents sticking and rust while reducing wear. By spending just a few minutes lubricating locks routinely, you can avoid the hassle and cost of replacing locks that have seized up from lack of maintenance. Keep your valuables secure and easy to access with smoothly operating combination locks.
