Morphology
The meaning 'a lock opened by a code' is directly and predictably derived from 'combination' (a specific code of digits/keys) combined with 'lock' (a fastening). This noun–noun compositional pattern is common in English and other languages, so a B1 learner who knows both constituents will readily understand it.
Etymology
Combination lock gets its name from how you turn dials to make the right combination of numbers so the little wheels inside can line up. When the numbers are in the correct 'order' the lock will 'open', so it means a lock that opens only with that exact sequence and not with a key.
