Sep 17, 2016 5:05 AM in response to cmonnowby pjspjs,Thanks that worked.. partially as diminished the problem.
My issue is mostly Q to P line.
I am convinced that it was El Capitan making the keyboard more sensitive, or a related firmware upgrade. My son changed the keyboard to English, and it got worse. I changed it back to Swiss French and it got better. If I flex the keyboard downwards the problem disappears for a few days, (Putting downward pressure on the middle of the keyboard).
Regards, Phil

Sep 19, 2016 1:21 AM in response to pjspjsby saveliev,I think it's just a hardware problem.
I have the same issue in my 2011 macbook air with the q-to-o keys.
The only long-term solution seems to be the replacement of the keyboard, but it's quite hard for me and I don't want to spend a lot of money for Apple's assistance.
It's a pity since otherwise the laptop still works great..

Sep 19, 2016 7:37 AM in response to savelievby spudnuty,Here's a picture of the front membrane contacts on a MBP that I posted earlier in this thread.
So as you can see the contacts here are all arranged and wired horizontally. Any crack in the trace will cause the downstream keys to stop working. (Not sure which way is downstream.)
Sometimes flexing the keyboard will cause it to start working again but a permanent fix involves replacing the keyboard. It's quite a pain to do the replacement due to the number of screws and the fact that everything has to come out of the MBP but the replacement keyboards are cheap now.

Sep 19, 2016 8:47 AM in response to spudnutyby pjspjs,I understand the hardware issue. However, my problem started with an update to El Capitan and related firmware fixes. I think previously the detection of the hardware (key functionality), by the software (OS) and related microcode was more fault tolerant. Since I reduced the key repeat speed. It has mostly stabilised. I am not saying it has gone away. I can live with it without having to change keyboards. For me the problem is a combination of poor keyboard design and poor software fault tolerance. Previous OS's were more tolerant as nothing else changed :-)

Sep 19, 2016 9:16 AM in response to pjspjsby spudnuty,Right on! That's why I'm still using Mavericks 10.9.5 and continue to do so on all my new installs. It seems unintuitive to me that an OS update would cause only a certain keyboard string to fail but I've seen weirder anomalies!

Sep 21, 2016 3:46 PM in response to gtashaby SegunLee,That is really strange because I had the same problem with my u, i and o. I tried the Option 5 times solution and all the other solutions on the Apple recommended pages and they didn't work. Then, I tried your method - Ctrl 5 times - and it worked. W T F indeed!

Sep 29, 2016 7:28 AM in response to MattyRayby rjjcvb,Same problem:
t y u i o sometimes does not work.
It seems that they work better when my macbook pro late 2011 is hot!
Sometimes by pressing all of them at same time couple of times, it starts to work again....
I suspect that this as something to do when they have changed my motherboard with newer version, but the said that is has nothing to do with that
Only was to solve this irritating problem is changed the whole upper case! 317€ (218,12€ upper case + installation)
With external keyboard all is OK....
I guess I'll just live with it for now.
