A team from UCSD came up with a way to steal keys without detection. Their SNEAKEY system used teleduplication to take an image of these keys from 195 feet away using imaging equipment, then managed to duplicate them with computer vision algorithms. You can read the details of the studies that were conducted in both laboratory and real settings on their site. The moral of the story is that even though these were the good guys, always keep your keys in your pocket when not needed.
