I have not worked on one of these 2015 12" models yet. I got one in with a missing key and a spacebar that works but is depressed on the right hand side. What I believe has happened is that the plate that holds the keys so thin that pressing hard on the keys bends in down preventing replacing the keys correctly and if they are replaced they are down and depressed (just like me looking at having to replace this keyboard ;-( . What Would like to know is if anyone has actually done this repair. Does it has screws or pegs. I did find the part at AliExpress https://www.aliexpress.com/item/100-NEW-… If it is possible to do, I will try to make a guide but wanted to ask first. I also could not find a replacement screw set. @danj
Yes, it’s possible to replace just the keyboard. This uses pentalobe screws to hold the keyboard in, no rivets. You won’t need to order any screws. Don’t screw the new screws in too tightly, otherwise it can cause other keys to be activated when pressing one key. Make sure you have a T4, and be careful when opening it. It will take about 1-2hrs. The MacBook will not boot after being disassembled unless the USB C charger is plugged in first, just so you know (gave me a heart attack before I realised this). You will also need to awkwardly test the keyboard before screwing it in by plugging it together and holding both halves of the MacBook, whilst plugging in the charger, so have fun :)
Do not replace the keyboard, it basically wrecks the quality of the machine. You can replace just the faulty keys.
