Chosen Solution
I have a late-2019, 16 MacBook Pro W/touch-bar which had stuff spilled into the keyboard. The laptop works in all respects, but the keyboard is very crunchy and hard to use so I’d like to replace it. I have found a used keyboard: “Apple A2141 MacBook Pro 16" LCD Keyboard/Battery/Fans Case Assembly” and the part includes the fans. From the iFixit teardown, the process looks pretty straightforward, but they do mention a problem with the TouchID sensor being directly connected to the logic board which they indicated would make repairs problematic. What does this mean and can someone who is capable of repairing any Macs (or PCs) from the early days to 2017-18 without a serious problem, replace this uppercase and keyboard and come away with a working laptop, keyboard and TouchID sensor at the end of it and does anyone have a video or the steps for this procedure?

Replacing the uppercase is a bit of work as you are stripping down the system and rebuilding it. I recommend you don’t attempt it. Its clearly a more advanced task. As far as the TouchID you need to be very careful as the ribbon cable is very delicate! If you damage it thats the end! Once you get the logic board out you’ll be able to see the screws which hold it in. The cable has a tricky route and is glued in a few places.
