Its Bad EffectsEdit
Its easy to see that keys are helpful by letting you into your house to get away from someone or even when you're jut to lazy to enter a password, but there are still some bad side effects of keys. If you die or get knocked out someone can easily take your key and go into your base. This'll be really bad if you have something valuable there like a drill with lots of money upgraded into it.
