Command key and zero (0) not working

Command key and zero (0) not working

I had an issue with the Command key and 0 not working, started intermittently. Then qaz and delete stopped working that too started intermittently. So I ordered a new top case. After a lot of screws and picking things apart and putting it back together again, I have a new keyboard. The problem is that Command and 0 is still only working intermittently. If I push both Commands and zero at the same time it usually get them going again. The question is what could now be the issue. The Command key does not work at startup either, so it most likely isn't a software deal. haven't had any issues with qaz. Appreciate any ideas or suggestions.

"Lets see if resetting the PRAM settings helps here. Reset NVRAM or PRAM on your Mac.

Also what App are you using that calls for a CMD - 0 (zero) I only can think of CMD - O (letter) for open file at the OS level."

"My Mid 2014 Macbook Pro has the exact same symptom — the right command key and the zero key intermittently don’t work.

Watching with the Keyboard Viewer, I have found that they (so far) will respond after some time if I simply keep them pressed down and just wait. In anywhere from 30-300 seconds, the keys seem to come back to life for a while so long as I keep using them. Once I stop using the keys for while, I have to press and hold and wait again.

Leads me to think the issue may be temperature-related as the only physical change of keeping those keys pressed is my fingers absorbing some heat.

Glad I didn’t try the upper case fix, thanks Kjell…that was next on my list! I tried the NVRAM reset, no luck too."
