Try calling Sentry first with the numbers on the tag maybe they will give you an overide combination
If you're not sure of your combination, you can retrieve it from the manufacturer in the following way:
You will need to fill out the form below, follow all instructions………. get it notarized and submit it to the safe's manufacturer
Please keep in mind that no combinations are available on the internet for your protection and security and after proving your ownership of the safe, the manufacturer is the only one that has the original combination on file and can release it to you and no one else.
If you need to speak to Sentry Customer Service to explain your extenuating circumstances, here is their contact information:
Customer Service: 1-***-***-**** (hours are 8AM-6PM Monday through Friday, Eastern time, but are subject to change). Fax: ***-***-****
If this is an emergency situation, your only other alternative is to call a certified locksmith/safe technician. After providing proof of safe ownership/identity, the technician should be able to retrieve your combination from Sentry on the spot if you don't have it. This would, of course, be a more costly way to proceed, but only if necessary. You can try any certified local locksmiths/safe technicians in your area or this company, below, which has offices nationwide; they may have a branch in your town:
