I feel like the risk of that actually happening is pretty low. The few that possess that skill with consistency are locksmiths…. I don’t know common criminals that have this skill in addition to having key blanks and a cutter, the wherewithal to slog through all of his posts and narrow it down to a place and then go to his house and use that key to unlock it. Seeeeeems like a stretch to me. Not to mention there’s another key in that photo with the actual code stamped on the face… even then it’s still a stretch.
It’s a defiant lock… so it’s not like the lock was an impenetrable fortress to begin with.
