Hello, and welcome!
Thanks very much for requesting me to help with your safes question.
Unfortunately, the only way to obtain the safe's code, because safe combinations are never available online for your protection and security, is by requesting it from the manufacturer, Sentry, and this will take at least 2 days, so if you need this document by tomorrow morning, it seems that may not work for you.
Are your parents not home, to provide you with the combination or open the safe for you?
When you request your combination from Sentry, you need to verify safe ownership with a Notary Form, after filling out the form located at this site, and continue to follow directions, then fax the forms to them with payment. As you can see, they offer expedited services for an additional fee:
The only other alternative, since this seems like an emergency situation, is to hire a local locksmith/safe technician to open the safe for you without ruining it, or s/he might have to drill to get into the safe, rendering it unusable in the future.
I wish you much good luck and please let me know if you need any further information.
Please be so kind as to rate my answer with positive feedback; that is the only way I receive credit for my assistance. Thank you very much!
