After flexgate fix and battery replacement, keyboard does not work
My Macbook Pro had a high battery cycle count and the flexgate issue where the display went blank when it was opened more than approximately 60°.
I replaced the battery and, at the same time, spliced in a new cable to fix the display. The machine now boots up and the display can be opened normally; however, there is no longer any response from the keyboard which had no issues prior to the fix.
The trackpad still works fine as does the touchbar. There was never anything spilled on the machine and no physical damage.
I reopened the machine, reseated the trackpad cable, and cannot see anything else out of place. I'm hoping this is a simple fix and I just missed something small, but I'm not sure what to look for or to test.
I have a "magic" keyboard for an iMac as well as another generic BlueTooth keyboard, but no way to connect to the USB C port on the Macbook, nor to connect via BT since I cannot log in. My next step is to get a USB A to C adapter so I can connect an external keyboard and try to at least reset the SMC.
What else do I need to consider?
