How to repair or replace the keyboard? Regards!

Apple offers free keyboard repairs! Keyboard Service Program for MacBook, MacBook Air, and MacBook Pro Unless you has a liquid spill I would let Apple eat the costs! OK, you want to do it as you just can’t get to an Apple Store or you had a liquid spill then you’ll need to replace the full uppercase assembly. 15” MacBook Pro Top Case/Bat/TP/US - Space Grey, Apple P/N 661-1316315” MacBook Pro Top Case/Bat/TP/US - Silver, Apple P/N 661-13164 These are new units, you might be able to find a recycled uppercase but these could be in bad shape and like need a new battery. So in the long run I would recommend getting a new unit. This series keyboard are very difficult to replace alone. I don’t recommend it!
