Keys are phallic symbols or male symbols and the keyhole represents the feminine or female. Together they can represent higher wisdom, unlocking the unconsciousness and new beginnings. If possible have a key hanging outside each doorway whether you use them or not. They can be merely decorative but very protective at the same time. A small key can hold just as much power as a large key.
