Oh, geez. Well, there are about eight copies of my car key (they all came with the car when I bought it), the key to the neighbor's house, the key to grandma's house, the key to the friont door of our building, the key to our apartment, the key to my storage unit, and then there are the nine keys on my work key ring. plus a bunch of random keys in a box that I can't remember what they go to.
