Morphology
church + key
Although 'key' evokes the idea of opening, the compound 'church key' refers specifically to a can opener and there is no transparent link between 'church' and the act of opening cans; the historical/analogical origin (tool resembling a large key) is not obvious to learners. A B1 learner who knows 'church' and 'key' would not reliably infer 'can opener' without prior exposure, so the expression functions as an idiom.
Etymology
Church key comes from one popular story: the small bottle-and-can opener looks like an old metal key that once opened church doors, so people joked it 'opened' drinks. That's why church key now means the small tool bartenders use to make a hole in a can or open a bottle.
