Problem in my friend's early 2011 macbook pro was unworking row of keys QWERTYUIO so I decided to figure out what was wrong there.
1. It was very dusty inside so heatsink was almost clogged and machine seemed to be very hot. I noticed heatsink sticked to keyboard black foil. But it wasnt that bad.
-2. I removed keyboard (70 or so screws, yes) and dissasembled it completely, every single key :-)
+2. I removed keyboard (66 or so screws, yes) and disassembled it completely, every single key :-)

-3. Next I took a close view for contact layer of keyboard and figured out what traces are responsible for non working keys and finally find a trace break! Im wonderin' how that break could happen, but it's a fact.

Im wonderin' how that break could happen, but it's a fact. There are at least 2 conductive layers separated by thin plasic layer, everything glued together so be careful when diggin' into...

-4. Now I had to reestablish that trace so conductive paint was helpful. I used Mechanic MCN-DJ002. Looks kinda terrible but worked. Dont forget to check if you successfully fixed that via. Be careful, that factory traces are very fragile.

5. When my broken trace was fixed I assembled back machine and now every key works fine.
PS this fix is very hard to do but in comparison to changing top cover for 300$ this costed me few hours of time and just 4$ for conductive paint. Its much faster just to replace the whole keyboard - this is my advice for everyone.
-PPS when you got multiple keys non working - the first that you wanna try is to check your keyboard connector and flex. If it doesnt work and you know how - check pcb vias from keyboard connector to chip that is responsible for that stuff, you need to get schematics and board view. If that was OK - you just get your new keyboard.
