The important thing had to pas a number of wards (road blocks) as a way to unlock the bolt.

Lever locks have a single or, far more levers inside their system. The lever has to be raised to a selected peak ahead of the bolt is often eliminated. Only the correct important can raise the levers to exactly the height needed.
