While talking to the cops about the incident described above, they said that these guys do this and go right to the owner's manual. Many people leave their valet key "hidden" in there. They just drive the car away if they find it. Otherwise they move on to the next target.
I see you're in NJ. This happened to me with my e46 M3 in Jersey City when I got it. At the time it was so rampant BMW sent me a sticker that said "No valet key" for my window. I hear Short Hills mall is also notorious for this. I also leave my glove box open now so they can at least see theres no key and move on.
