                2 questions: 1) Can it be opened with a strong magnet given it doesn't have a dual key system? 2) Can it be bolted to the floor or floor, or just floor?
                ByAug 1, 2024
                1 Answer | 
                Answer This Question

                Hello AdamQ, the safe can not be opened with a strong magnet but it does come with an override key plus the electronic lock. This unit has mounting holes both on the bottom of the safe and also the back meaning that you would need to mount it to the floor and wall at the same time. If you have any further questions please feel free to reach out to our customer service team. They can be reached at 888-792-4264 Monday through Friday from 8am (cst) to 5pm (cst) or via email at cs@saproducts.com.

                  Questionable Digital Keypad
                  I read reviews by others that noted the battery falls out, it doesn’t even stay in place on the safe I received. Strip of duct tape, now it stays in place. My biggest complaint is the touch pad is not secure in place. The bottom clip does not engage to hold the panel cover in place on and it falls off at will. Inside of safe is nice, good size, light has some benefit but still suggest a flashlight. The quick start documentation was easy to follow and worked well.

                    Excellent safe. So far, I'm quite pleased with this purchase. It's very solidly built. The directions for set up were clearly written and the needed 9v battery was included. It's certainly heavy enough to discourage anyone picking it up and running off with it before I get it securely attached to the floor or wall. In hindsight, I wish I had gotten the next size up, but then again, it's mostly important paperwork that I wanted to protect, and that all fits nicely.

                    The safe was as advertised, easy to setup and program the digital lock. No defects or problems with missing parts, so that was good.

                    THE SAFE WAS DELIVERED AS PROMISED. I CASE YOU FORGET THE COMBINATION FOR THE DIGITAL LOCK. IT HAS A VERY LONG KEY YOU CAN USE. I WAS GLAD FOR THE KEY BECAUSE IT'S EASILY IDENTIFIABLE.
