There are a few different ways that you can open most safes, including Sentry safes. A safe is basically a locked metal box where you can safely and securely store valuable items or items that you don't want damaged in any way. You can typically open a safe by using a key or by entering a specific combination. If you don't have a key for your Sentry safe, then you'll need to know the combination before you relock it. Keep the safe open until you get the combination. Otherwise, you risk not being able to open it again and your belongings and valuables will be stuck inside.
Navigate to the "Recover Your Combination" page of the Sentry website.
Enter your Sentry user name and password if you have one. Then you will be able to view the registered combination for your Sentry safe. If you have no user name and password, skip this step.
Click "Download Notary Form" to request that the combination for your Sentry safe be mailed or faxed to you. Fill out the form in its entirety.
Send the completed form, along with a $20 check, to Sentry. Send these materials to 900 Linden Ave, Rochester, NY 14625. You will receive the combination by mail or fax, depending on which method you indicated on the form.
Lift the handle of your Sentry safe upward slightly and close the door once you know the combination. After you close the door, release the handle. This will relock your Sentry safe.
