Well i have a sentry fire box, now granted an angle grinder would own one, you can grind off the wafer, find a nice medeco cam lock on ebay for a resonable price, drill two or three or how ever many holes in the bottom of the box, maybe a hardend steal plate.. you can even use iron or w/e is laying around and us that to reinforce the bottom, and secure it to cement or a solid stud, i mean it seems like alot of work but really only took me 15 mins for the holes and securing, i am still looking for a cam lock that will fit, it was jsut a test project but proved effective with just junk laying around the house, even tested it with a crowbar and since it was in the cement with only two bolts and some metal plate.. just laying around proved great from prying off, and if a good lock is on will resist a quick pick open.
Granted the term if someone wants it bad enough they will mostly get it or get caught trying, even so it was just a cool in home project and proved effective, i would always buy a safe for valuables. But for 10$ for the box worked great
