How To Open A Safe With A Key. Request a key replacement from sentrysafe, or use a nail cutter, paper clip, or drill. Some manufacturers require a notarized letter to prove safe ownership.
You have access to your valuables. Enter your new combination on the safe's interior keypad and hit the set button. You will need to give the model and serial number of the safe when you contact the manufacturer.
Keep your sentry safe on a sturdy surface.
Manufacturers usually print the model and serial number of the safe near its door hinge. The manufacturer will mail you a duplicate key by mail to replace the lost key. Some keys can be copied, but we recommend a new lock with 2 new keys. In some cases, the safe technician may need to drill out the lock to gain access to the combination safe.
