Some keyboard keys not working

Hi, I recently replaced the battery on my MacBook only to find that some of the keys were triggering other keys around them as well. I did unplug the keyboard during the battery replacement, so I suspected the connector was possibly bad. Now I’ve replaced the keyboard, and am encountering the opposite issue where certain keys are completely nonfunctional. Attached are microscope pictures of the damage I suspected on the old connector, and pictures of the new connector in case there’s something I don’t see. It looks very different than the old one, but some keys work so I’d assume that’s not related? Any help is appreciated. Thanks!

Edit: I did replace just the keyboard, not the full assembly.

It seems like only the power button is working now. I'm new to all this, so I'm completely guessing here, but is the power button handled on the same IC as the rest of the keys? If it isn't, does that mean I have a board issue?

I fixed it! Turns out the problem was caused by peeling off one of the films on the keyboard cable. Two of them were covering adhesive, while the third was an insulator not intended to be removed. I slid this piece into the ZIF connector, and slid the keyboard cable in above it. Everything works great now!

An additional wrinkle, for others. Some models, at least of the 1278, sometimes have a thinner keyboard flex than is usual. Mine was .007" instead of the .009" of the replacement. The .009" flex WILL NOT fit into the connector. I had to call a dozen Mac repair shops before I found one that knew about this. They were able to provide the proper keyboard.

So when you get your new keyboard, check the flex to ensure it fits. Otherwise, you might wind up doing the job twice, as I did.
