Morphology

key + fob

The meaning is directly inferable from combining 'key' (an object for opening locks) with 'fob' (a small electronic access device): together they denote a small device associated with keys that grants access or unlocks systems. This noun-noun compositional pattern is straightforward and cross-linguistically common, so a B1 learner who knows both constituents would understand the MWE.

Etymology

Key fob comes from a simple, old idea: a 'fob' was a small pocket or tag people used to carry a watch or coin, so a key fob is the small tag or ornament you attach to a key to make it easier to hold or find. That's why it means 'a small item on a key ring'.
