I've noticed a lot of people on here curious about key holders, but nervous to take the plunge. I use the below safe (slightly different model) to hold my keys. It's 100% secure and takes your mind off your device. Seriously, this little safe ever so gradually made it so when I do squirm or blush, I just smile a bit and that's it. It's like once you stop trying to touch yourself, this all becomes a very "chill" cake walk. I still unlock sometimes (let's be real), but it's because what the hell why not or things just get lonely or boring. That's the single life in a nutshell.

Is there a regular power connection or does it run solely on batteries? If it is just on batteries about how long do they last? If you can program a new 8 digit code and then be locked out for a few day it might be a good fit for something like chaster. By the time the safe would let you put the code in again I would have forgotten it.
My wife locks my emergency key in a small safe & keeps the code in a sealed envelope - very effective- so close but so controlled.
