Locksmithing/how to unlock safe


The only information that I have is what on the front and the handle and that is Underwriters Laboratories Inc. Safe 451128. Then beside that is the word fire classification C and on the handle 82591. I would like to know if there any way to get the combination to open it?

Hi Diane,

You haven't provided me with any useable information.   UL is simply a "STANDARDS" testing agency.  They have nothing to do with any manufacturers or combinations associated with any safe.   In this case your safe is built to a "Fire Classification C" standard, which is a 1 hour resistance rating.

If you (or we) cannot determine the manufacturer AND a serial number for your safe, then you have no where to go to check for a possible original combination.

That being said, manufacturers NEVER publish information concerning serial numbers or combinations, and many of the companies only maintain records going back about 10 years or so.  Many of the older manufacturers have gone out of business, so it may not even be possible to contact them for a record search.

So currently, with no better ID for your safe, you have two options available, you can dial all of the 1,000,000 possible combinations for the lock on your safe, or you can have a safe technician from a local safe company open it for you.

If you don't have a local safe company, let me know where you are located (zipcode) and I'll see who I might know in your area.

Sorry the answer isn't better, but if combinations were easily accessible, they wouldn't be very safe.
