You are right, and that's why I think it's a shame that the opportunity wasn't taken to alert people to that idea. I spend a little time collecting high res photographs people post online of their keys (happens all the time) and do enough digging to associate those keys with an address. I'm a good guy, though and just try to raise awareness. And yes, they do. There have been a handful of concepts to do exactly that. Check out the Van Lock[0] for one, which is almost exactly what you are describing. [0]http://www.safersystems.co.uk/Images/Vanlock.gif http://www.safersystems.co.uk/Images/Vanlock.gif
