Morphology
The compound is fully compositional: 'lever' specifies the type of 'tumbler' (the tumbler used in a lever lock), so the meaning is directly derivable from the constituent senses. Although the term is technical, the noun+noun combination follows a straightforward modifier–head pattern that a learner who knows both words can infer.
Etymology
Lever tumbler is a flat metal part inside a lock: imagine a small lever that works like a little tumbler or seesaw, which the key must lift. When each lever tumbler is lifted to the right height, the lock can 'open', so the name shows the part that must move for the lock to work.
