Morphology
The meaning 'to require someone to remain indoors' is directly and compositionally built from 'keep' (to retain or continue) + 'in' (inside), so a learner who knows both words can infer the action of keeping someone inside. This verb+particle pattern is common cross-linguistically and follows ordinary spatial/compositional logic, making it readily understandable to a B1 learner.
Etymology
Keep in comes from the simple picture of someone being kept inside: to keep (hold) someone in (inside a room or house). So it means 'to make someone stay inside' or 'to keep someone indoors'.
