Linus Yale patented the modern pin tumbler lock in 1861, and hotels took to it immediately. The clever part was never the lock; it was master keying. The same door opens for a guest with one key and the manager with another, each cut to a different depth of authority. It solved the problem every growing building has, and introduced a new one, because now a single key opens everything.

The hard part was never the lock. It's deciding who gets which key.<
