Lost combination and also lost the keys,I need at leats replace the keys,I have the serial and number of the key

You do not need to go to a locksmith - you can get a new key much more inexpensively by contacting Honeywell (the parent company for Brinks safes) at 1-800-223-8566

When you call Honeywell, you will need to provide your safe's model number (5059) and the serial number (usually found on the right of the safe, near the model number).
At the company's discretion, sometimes they require a notarized affidavit confirming ownership. There is a fee for a replacement key (it was $15 last time I checked, but may be higher now), but it is much less expensive than going through a locksmith (who will generally just do the same thing as described above!)

I have a sentry safe 1250 .83 cubic and I have the key I was using the safe for awhile without the combination and just the key but now the key wont work and someone messed with the combination part which I dont know the combination i dont know what to do and I dont wanna trash this safe
