I take my house keys and other personal keys off of my keychain (or simply use a car key only) when I leave my keys with them.
That way you don't have to worry about leaving your house keys with someone you don't know.
I'm also paranoid enough that I write down the mileage of my car before I leave it and compare it after I return - never had any problems.
