I have a similar problem but was able to get into my safe. My lock (although not labeled) appears to be Yosec lock from China. I think they cost around $9.00 but you have to buy in lots of 100 each. So lets get a group buy together.
This is what the lock looks like.
I would like to get rid of this lock but it is orientated 90 degrees off a standard lock. The bolt comes out of the long side of the body not the short side.
I have found these strings to follow for Patriot Safes: Ridge Runner Outdoors, LLC, Old Glory Safes, Michael Proctor, and Tim Merlo. Being the weekend I have not been able to follow up with a phone call. Looking at other safes products I think see a lot of safes that look like mine and a lot of safe companies that are located in California. My gut tells me they all import them from the same place in China. Ridge Runner's address is a "Mailboxes Etc." or something like that. The kind of place where you rent a mailbox so no one can find out where you really are and you can easily dodge creditors.
A little more research. It appears this is who the Patriot Safe was made by http://www.cn-aipu.com.
