If you get an aftermarket keyboard , don't peel the blue backing on the ribbon cable. I mistakenly thought it was a temporary factory protective cover, but it's in fact part of the cable.
Pull straight OUT not up.
Don't use tweezers for this (???) Pull straight, starting gently and a little firmer until it gives. 2014 doesn't have the retaining tabs
Put the spudger under the very centre where you see the cutout and be gentle !! It does in fact pry upward the wire itself is very fragile.
This wording I found quite confusing. They just mean when putting the lid back on that you just removed in the previous step, push here.
