Bill's Lockmobile

I walked out the door, it clicked, and I remembered my keys were still upstairs... Went to the police, they gave me Bill's card, he came right away. Tried the cheapest way - picking the lock in a number of different ways - first, that didn't work; my wife had bought a good lock! So then Bill drilled it out, and got me back in my house, and left me with good instructions what the cheapest way to restore the lock was.
