A warded bit key lock operates using a specific set of components that facilitate the locking mechanism while providing a means for the key to align with the internal wards. The latch bolt is an essential part of the lock, as it secures the door and is typically operated by the key or a thumb turn. Shackle pins are used in padlocks to hold the shackle in place, thus playing a critical role in the security of various locks, including some warded locks. Dummy plates serve as non-functional components that provide a finished appearance to the installation but do not impact the lock's operation.

The lever tumbler, however, is primarily associated with lever locks, which are distinct from warded bit key locks. In a lever lock system, the key manipulates tumblers (levers) that must be lifted to a certain position for the lock to disengage, which is different from the way a warded bit key unlocks a mechanism by aligning wards. Therefore, identifying this component as not being a part of a warded bit key lock clarifies the unique operational structure of these locks.
