I have found a very simple system of protecting my house from being robbed. Make two statues. Place them near the entrance of your house. When you leave the house, move them to block off the little entrance hall. That way nobody can steal anything even if you left the door open. And if someone that shouldn't has your key they can't steal anything either.

It's very simple, and as far as I can tell, foolproof.
