BLC, sorry to here about your new year start.

It's a shame, but I think you're getting good advice here in terms of getting your key re-programmed, and changing your locks. I haven't had this experience in a long long time, but I get that occasional teen age prank. I've thought about putting a remote camera pointing outside. Something to consider.
Good luck.

+fireamx, interesting story. That is just plain laziness on the police's part.
