I get what the author is getting at. But this particular example doesn't really help with the conclusion. The solution is still about locks, just that the 2 locks are now linked together.

There are no locks in doors at all. There is a single mechanism physically connecting the doors together, so that neither can be opened, and that can only be engaged and disengaged from the inside.

  How is that mechanism not, itself, a lock? It's an unusual (and well suited) kind of lock, sure, but still a lock.

    Try pointing to the part that is the key that unlocks it, and you will see. (-: Yes, strictly speaking the headlined article is likely talking about door bolts not locks.

      There are plenty of locks that do not use keys, e.g. a keyless deadbolt.
      - JdeBP 8y ago
        No. The key that unlocks a "keyless" deadbolt is the code that one types in.
        amalcon 8y ago
        That type exists, yes. There is also the variety that is simply impossible to unlock from one side.
