I replaced the battery in my Macbook Pro and now certain keys on the keyboard won’t work such as the “enter” key and the “delete” keys don’t respond. I can use a bluetooth board just fine. Any advice on what to do would be greatly appreciated. Don

When you where lifting the center cells you may have damaged the keyboard ribbon cable. Lets see what other keys are failing, go to your keyboard preferences and check off show characters & emojis. That will allow you to see the keyboard viewer so you can walk the keys to see which are failing. Post the list here so we can see.
