Control, Option, and Shift keys (on left side) do nothing.
I just replaced the logic board on my sister’s Macbook Pro 15” mid 2015 Retina. Now the left side Control, Option, and Shift keys are not functioning. The keys do not register in the keyboard viewer. The replacement logic board was purchased from iFixit, so I’m assuming it should be fully functional.
- I’ve tested in safe mode, a new admin profile, and even booting from another MacOS installation on a USB stick.
- I’ve reset the NVRAM.
- I’ve reset the SMC (by unplugging the battery and holding the power since the necessary keys do not work).
- I’ve re-seated the keyboard connector multiple times (and the trackpad connector for good measure).
Questions:
- Is there anything left to try?
- Which piece of hardware should I be looking at?

Why was the logic board replaced ?

@arbaman The laptop stopped charging. It worked fine while it slowly died, then couldn't be charged at all. We also replaced the Magsafe 2 board during that process and I bought an expensive genuine Apple charger since she was using one someone had given her. It had wire exposed and looked to be in very rough shape.
Could it be possible that the keyboard was damaged at the same time as the logic board? It went unnoticed until we replaced the logic board and I watched her struggle to log into internet accounts for an hour before she realized the shift key was causing her to type passwords incorrectly.
