i have a cannon fireproof safe with key and tumblers. not sure of the size but its big and heavy. with a good strong dolly and four guys we moved it up a flight of steps without a problem. my advice is not to let the weight discourage you, and like was said before, get the biggest one you can afford, they fill up with valuables, other than guns, before you know it! also, the key and tumbler doesn't bother me as i don't get into it every day! good luck.
