mine was a round key and i was hopeful it was full of gold or silver bars when i had a locksmith come open it. 100 dollars later i had 4 keys and a empty safe. the locksmith said he bought a safe at an auction that was locked with no combination. he put an autodialer on it and after a couple of weeks he had an open safe with valuable contents. luck of the draw.
i hope you figure out how to get it open.
