[image|1259957]I have a mid 2012 macbook pro unibody 15" and the left shift/option/control keys do not work. Upon inspection of the keyboard ribbon socket on the logic board, the 3 first pins appear damaged. These 3 pins control those keys, according to the schematic I found online. Based on these observation, I conclude that in my case, it is hardware problem.
