Review on Secure Your Keys with the Master Lock 5400EC Lock Box, Black, 5 Key Capacity by Michael Rasberry

Definitely don't use this on keys that protect something valuable, especially your house! There are videos on the internet about how easy it is to pick this lock and it could happen to you. I can't stress this enough. Last night we were woken up by an intruder at our home cutting it off our main gate and opening it (probably following a simple google video with instructions) using the keys inside to enter our home. Luckily no one was hurt but trust me you never want to experience this situation alone. Find another solution if you want to keep your house keys for others, preferably one that the whole internet can't open!
