102 has carbon impregnated silicone rubber domes like calculator or remote buttons.
With care it's possible to lift the top of the key switch body off and lift out the rubber dome, and see if the contacts or button are dirty. Maybe use some deoxit with a q-tip to clean the contacts, maybe clean the carbon pad. I had a stuck T key where everything looked fine but the carbon pad maybe just looked worn. I swapped the rubber dome with the right-shift key (a key that I don't use as much, and has a duplicate on the left anyway, and was much less worn because all the previous owners probably used it less than T also) and afterwards not only did the T work, the right shift still worked! To get the keyswitch apart, I don't know how to verbally describe everything clearly.
