10 types of ways to  Lubricate a Lock

All of us have a lock in your house or car. Sometimes that lock decides that it isn’t going to budge! Maybe the key won’t even go fully into the lock.

Before you end up breaking the key in the  lock, try one of these lubrications to fix your problem.

GPM Locksmiths based in Milton Keynes have over 14 years experience in repairs to locks.  

1. Teflon Aerosol Lubricant

In addition to the dry version, you can get Teflon-based lubricant in aerosol form. This option is easier to apply. This spray creates a thin coating inside the lock. The coating repels dirt & dust. It has no silicone and is  long-lasting.

2. Teflon Dry Lubricant

Teflon-based dry lubricant is preferred by some locksmiths over other options.

It’s a great option because, as well as  lubricating your lock, it repels water and dust. Meaning that once you fix a lock with this type of lubricant, you can expect the lock to be in good shape for a long time.

3. Powdered Dry Graphite

Powdered graphite comes in small tubes. You can squeeze the product into the lock.But be warned it can be messy. If you have carpets by your door I would advice covering them over before use.  

4. Graphite Lock Fluid

Graphite lubricant is also available in graphited fluid form. Using this helps repel moisture so it’ll keep your locks from freezing. Plus also protecting in high temperatures. Also it’ll help keep rust away.

5. Pencil

A cheap way to help with your lock, Rub the point of a pencil along the edge of your keys until it’s covered in a coat of graphite. Next, place the key in the lock. This will help coat the locking pins with the graphite from the pencil 


6. WD-40 Specialist Lubricant

Although tempting to reach for regular WD-40 to lubricate the locks in your home, it’s probably better if you don’t.  Regular WD-40 is an oil based spray that attracts dust and dirt and dries up over time. 

Instead you can use WD-40 Specialist lubricant. This repels dust and dirt and you can safely use it on any type of lock

7. De-Icer and Lubricant

If you live in an extremely cold area, consider de-icer and lubricant combos. It’s great if your car or house lock is iced over because it’ll de-ice and lube it at the same time. 

Typically, using the de-icer and lubricant once should be enough to keep your locks from freezing again for some time.


8. Non-Toxic Mineral-Based Lubricant

If you’re sensitive to chemical products, you may wish to use a non-toxic, mineral-based lubricant. These will still repel dirt and dust and also have rust inhibitors to help your locks last for years to come. They can also prevent your locks from freezing.

9. Synthetic Oil with Syncline (PTFE)

Synthetic lubrication oils with tiny Syncline (PTFE) powder is an option for your stiff lock. The solvent in the oil carries the dry powder. Once you apply it to your lock, the solvent dries quickly, leaving the powder behind. The layer of PTFE offers the lubrication you need for your locks, and it doesn’t attract dust.

10. Proprietary Lubricant

Some companies produce lock lubricants with a proprietary blend. Although they keep the contents a secret, it’s known to be a “proprietary blend of base oils and solvents.” It seems to be a powerful solution, especially for super old and rusted locks.

If you’re having a hard time fixing your lock even after applying lubricant you feel it needs a locksmith to look at it. Please contact GPM locksmiths today.
