If you do not regularly clean and lubricate your safe, it can lead to a buildup of dirt, dust, and other debris that can cause your lock to seize up or jam over time.

How to Lubricate a Combination Safe Lock in 6 Easy Steps

Step 1: Remove the Safe’s Door

This is the very first step since it is next to impossible to lubricate a safe without removing its door. So first you have to remove the safe’s door by twisting or unlocking it. But you have to make sure that you remove the door of a safe that contains an open combination lock.

Step 2: Remove the Combination Lock Assembly

After removing the safe’s door, you need to remove its combination lock assembly because this is what you will lubricate, and your first step is just a preparatory one. To remove it, simply unscrew a few screws attached to the safe’s door.

Step 3: Clean the Lock Assembly

Next, you have to clean the combination lock assembly with a soft cloth and remove all of its dust and dirt. If there is any buildup in or near the keyhole, you can wipe it away with a piece of compressed air or a cotton swab dipped in gun oil. Once you have cleaned the lock assembly, you can proceed to the next step.

Step 4: Apply Lubricant

The fourth step is where you will apply lubricant on your combination safe lock. This is important since it will keep the moving parts of the mechanical lock from corroding and rusting. Make sure that you use a small amount of lubricant, just enough to cover all the parts that need to be lubricated.

Step 5: Replace the Combination Lock Assembly

Once you have finished applying lubricant and wiping off any excess, you can now put back in place your combination lock assembly. This process is usually easier than removing it since, most of the time, all you need to do is to screw it back in place.
