Unfortunately this is not something you can simply get a key for online, for obvious security reasons, otherwise anyone could break into your home or steal your safe and then just retrieve the key to open it, rendering the safe useless.
What you'll need to do is fill out a form, have it notarized (to prove ownership) then send it in (along with a check) to Sentry. They'll mail you back the original keys if applicable and/or the override code.
You can get the form here: https://replacements.masterlock.com/media/resources/notary-form.pdf
There are instructions on it for sending the info in by mail, or you can pay the fee online and fax/email the form after it is notarized.
I'm sorry there is not a quicker resolution possible, this process is in place to ensure security, so that not just anyone could get a code or key to your safe.
