This safe is not a fire proof item.

Yes, although, I did not know how I was going to botl the safe into my closet. Did not have a chance to try.

Technicaly it is front opening, but I think you can almost use it either way. Mmm, good question.

You will need both. Once you enter the passcode on the keypad, you have about 5 seconds to turn the key before the lights reset. I put the key in and get ready, then enter the code so I can turn the key right away. The key will not turn without the passcode. After the lights go out you can lock it, but you will need to re-enter the code if you want to open it again. You pick the code, and it can be anywhere from 1 to 8 digits long. Setting or changing the code is simple. You can always by-pass the code with the master-key (for dead batteries, or forgotten code). They supply 2 regular keys, and one master key.

Too small for a laptop unless it is a real old one with small screen.

Dimensions given are exterior dimensions. Subtract 5/16 inch from each dimension for interior size.

This safes falls under the category of "Anti-Theft" therefore, has concealed hinges so that the door of the safe cannot be easily removed. It also bolts down so it can't be lifted and carried away. Most anti-theft safes do not have a fire rating. If you need a fire safe look at safes under the category of "Fire safe" not "Anti-Theft" safes.
