I mostly use it for passport and various IDs I need to keep safe. Certainly good for the price. The lock is kind of weak but will hold up against light tampering, but I purchased it more for being fireproof than secure.

I'm assuming electronic keypad won't work at that point.** A: Buy the version that uses a key **Q: what happens when battery dies? how do you open safe?** A: The safe has no electronics and there is no battery. It is entirely mechanical. **Q: My electronic keypad one didn't come with a key? Was told it did. Could others let me know if their keypad ones did or didn't?** A: No physical key. What you get is a key code which should be on th back of instruction book. Use this to unlock box, then rest using paperclip and follow instruction to set own unique code.

I mostly use it for passport and various IDs I need to keep safe. Certainly good for the price. The lock is kind of weak but will hold up against light tampering, but I purchased it more for being fireproof than secure. ### ⭐⭐⭐⭐⭐ First Class *by A***D on 7 July 2026* First Class ### ⭐⭐⭐⭐ Useful size for A4 papers *by N***S on 12 May 2022* Bought for A4 documents and thankfully A4 documents provided they aren't in files fit. Some paper document folders full of A4 fit quite well as do envolopes that take A4 papers. As expected of Master Lock the lock and even the locking mechanism and opening catch are rubbish. Check out the LockPickingLawyer's youtube channel if you are under the illusion that Master Lock make anything thats difficult to get into. Well I'm wrong it was very difficult to open when it wasn't even locked. The mechanism is poor and if you don't press the opening lever just right (you need to press the part nearest the lock quite hard) it won't open. That discovered and not being worried about security only fire it seems to be the best item for size in its price range. Edit> Think I should add that the weight of the thing is a major downside. You need to plan where this will go put it there, pehaps bolt it down (there are internal marks for doing this) and then never move it again. Did I suggest it was heavy? Originally I'd planned to put this in a location where I'd need to move it to get at the contents, due to the weight this isn't going to happen. ## Frequently Bought Together - MASTER LOCK Fire Security Safe [Fire & Water resistant] [Large] [Digital Combination] - CHW30300EURHRO - For A4 Documents, Electronics, Etc - Fireproof Document Bag Legal Size: 15" x 11" [2000Β°F UL Certified] Protect Birth Certificates, Contracts, Legal Papers, Cash, and Other Valuables - Water and Fire Resistant File Bags - SentrySafe Fireproof Money Safe with Key Lock, Black Lock Box with Portable Carrying Handle for Travel, Exterior: 14.3 in.
