Got it from my grandparents 5 years ago. Only ever opened with key. Key stopped working suddenly, tried every troubleshooting step google told me to.

I also have the combination , but after trying every possible sequence, still no luck.

Hoping someone might be able to point me in the right direction, thanks in advance

Anyone know how to Crack this without destroying it?

This has been bolted to the floor of a commercial space that I have been leasing for over 25 years. I have no way of contacting the business owner who leased the space before me. Any suggestions on how to open it?
