“The Perfect Lock”

Tom Vanderbilt searches for it, but comes up empty:

What you are buying, in essence, is time. This is how locks are rated, by agencies like the Underwriters Laboratory: How long will it be able to withstand a variety of attacks. “I have always been happy to acknowledge any lock can be compromised,” Field said. “It’s just how much effort is someone going to take.”

“Anyone who says they have a lock that can never be picked is fooling themselves,” he continued. “There will be a compromise of some sort.” I was unsettled to hear this from a maker of locks, and I wanted to press him: But what about the perfect lock? What if money were no object? But I began to see I was on the wrong track. “Why would you want this elaborate thing when you’ve got windows on the first floor? People would smash windows and come in,” he said. “All you want is something that will show you a sign of forced entry. You want to protect things. If someone does break in you’ve got the insurance—that’s part of your risk management.”
