House owner, part 3

So everybody has been telling TBO and I that one of the first things we need to do is call a locksmith to come and change out all the locks. Seems like a reasonably sane task to accomplish. We have 3 doors and 1 gate that have locks (although I had forgotten about the gate), and a total of 6 locks altogether. When the locksmith arrived, however, he told me that for just the "medium level" of security he would charge me $110. That would be per lock, folks. Plus labor. Ack! I decided to get 1 lock per house door, and the grand total was still just under $500.
File under: amount of money I didn't expect to pay out for this.
