Stalwart Electronic Safety Lock Box

We’ve used these to keep the kids from stealing each other’s money. Works well for that purpose. However, will not work nearly as well against a determined adult who wants to get at whatever is inside. YMMV.

I was going to ask about this. Is there a “back door” way for me to get in if I give one to my 10 yr old daughter?

eta: never mind, I did something crazy and read the specs. 2 keys included for code bypass.

Is this waterproof and/or somewhat fireproof?

No. Not this level of lock box.
