Human: can you tell me how a key works to unlock a door?

Assistant: Sure, a key works by fitting into a lock.  The key might be a standard-sized key, or it might be a key that’s custom-sized for a specific lock.  In either case, the key has teeth that match the teeth of the lock.  The key can turn in the lock, allowing the door to open, or it can turn and push the lock mechanism, allowing the door to be locked.

Assistant: The key is an important safety device.  A door with a key will open only for the right key, and will close only if the door is locked.  It will also help you to keep the door closed, by providing a weight on the door to help it stay shut.
