Morphology
The meaning 'an important or essential function' is directly derivable from combining 'key' (fundamental, vitally important) with 'role' (function or position). This adjective+noun compositional pattern is common in English and across many languages, so a B1 learner who knows both constituents will readily infer the MWE's meaning.
Etymology
The phrase key role uses the image of a key that opens a door and a role as the part someone or something has. Because a key is needed to start or unlock things, a key role is the part that makes the whole thing work, 'an important or essential function'.
