Macbook Pro 2019 (15 inch) - 5 T G B - keys not working?

[Nino88]

Hi,

After using my MacBook Pro 15 inch. from late 2019 with the butterfly keyboard for 3 months now. I am facing some problems.
Keys are not stuck, still clickable but not working. When I Click FN, 5, T, G, B these keys do nothing and do not work.
I am really pissed and upset.. that I paid so much money for a laptop and failed after 3 months.

If I take it for repair they will replace it with the same keyboard and face the same problems over and over again. Is there any possibility that the would give me the latest Macbook out of service?

Is there way that I can solve this?

Those keys (5,T,G,B) are a more or less vertical line, and would be linked to the same line on the key encoder matrix (encodes the key press, so the computer knows how to respond). That line is dead - so the only fix is to replace the keyboard.
The keyboard will be replaced under warranty. You will have to call Apple for the warranty repair, or you have to wait until the Apple stores open again. Unknown when that might be, but AppleCare phone support will give you a way to proceed.
An encoder line is not usually the first kind of fail on those keyboards, so you should be OK with a replacement keyboard.

Only marginally related to this, but: yesterday the 8,i,k,«,» and the bottom arrow keys on my MBP stopped working. Sounds suspiciously like this key encoder matrix thingie as well, right?

You're probably correct...

Must've been something else, as the keys are back after some shaking of the MBP and pressing on the bottom plate.

I had a problem with 5tgb keys not working. Except when the laptop is hot, like when I actually use it on my lap, those keys would work again. I suspected it wasn't the keys but the keyboard connector that had the issue. Sure enough, I opened the back plate, found the keyboard connector, pulled it out, put it back in, then pulled it back out slightly so the contacts are in a different position, and now it works again.
