The A-key is affected on the surface book 2 keyboard, but only when pressing it harder than usual. It makes a “click” sound and as if it got stuck a couple of milliseconds. Not sure if this is a major problem as the button is still working and sounding not unusually when typing ’normally’. Is it an issue with the rubber cup or key hinge/cap, or rather an issue with the key mount/ mounting clips, which are not easily replaceable with a key kit?
Minor plastic spike in the key mechanism, not a problem in any way.
