The Master Lock safe with product ID LFW082FTC does not come with a key for opening in the event of a code panel malfunction. It only uses a combination to open.
Hello, pre-drilled holes for floor screw fittings only. But you can drill your own holes on the wall side. However, it has a plastic interior panelling.
That depends on the price of the Bitcoins: If you have more market value, then the coins are bigger, i.e. not as many Bitcoins go in as if they are worth less. I would also watch out: If you store a lot of Bitcoins with less market value in it, and suddenly the value increases, then it can "block" the Bitcoins in it, edge them, bend them or maybe even blow up the safe! That's why I would always put a wet army wool blanket over it, so that nothing flies away or could catch fire in the surroundings...

Good day. The battery compartment of the safe is on the outside and can be opened in an emergency by means of the factory code. You can find the manual under "Downloads", page 9.
The safe should not be fixed to a wall as this will affect the fire resistance. Therefore, this safe is fixed to the floor. You can find detailed assembly instructions under Downloads.
