Morphology

ignition + key

The meaning is directly derivable from combining 'ignition' (the system that starts an engine) with 'key' (a metal instrument used to operate locks), so a learner who knows both words will understand it denotes the key used to operate the ignition. This noun–noun composition is transparent and cross-linguistically common, making the expression predictable for B1 learners.

Etymology

Ignition key comes from the word ignition, meaning 'to make fire', and the key that turns a switch. In early cars a key turned a device that made a spark or small flame to 'start' the 'engine', so today the phrase means the key used to start a vehicle.
