Chosen Solution

My MacBook does not work from 1 to 9. I decided to exchange keyboards. I bought a new keyboard paner for my MacBook. how do i replace the keyboard panel  my MacBook Pro 15" Retina. Do you have a recommended workbook?

The keyboard by itself is held in by pop-rivets that hold the keyboard into the MacBook’s bottom assembly chassis. To remove them they require lots of force to push against these pop rivets, I haven’t had much luck on the A1502 models as they are quite hard to remove cleanly without leaving partially broken pop rivets which require special pliers to remove carefully. You’ll need the small phillips screws that are used on the A1278 models for the keyboard. Might want to check Youtube to see how it’s done, e.g search A1502 keyboard replacement guide
