How to Reset Passcode of Masterlock Combination Portable Personal Storage Safe
Question:
How do I reset the combination lock
asked by: Jennifer
Expert Reply:
In order to reset the combination on the Master Lock Safe Space Portable Storage Box # ML5900D, you will need access to the inside of the box.
The reset lever is a small, light gray lever on the top left hand side of the combination dial. You will need to push the lever to the right while setting a new combination. I have attached a photo showing the location of this lever for you, as well as a product review video that may help.
If the box is closed and the combination is forgotten, unfortunately there is not master re-set or any way to reset the combination.
