Morphology
lock + up
The meaning is directly built from 'lock' (to fasten or secure) plus the particle 'up', which here signals completion/intensification and confinement; a B1 learner who knows both words would readily infer that it means to secure or confine so someone/something cannot leave. This is a regular, compositional phrasal-verb pattern in English and is therefore transparent.
Etymology
Lock up comes from the simple image of closing a door and turning a lock so nothing can get inside, with up showing the action is complete. That's why it means 'to secure' a building or valuables by locking them.
