Hello all! Thank you for taking the time out of your day to help out! So the question I have is, does anyone know how to replace the “rubber cup” under the butterfly mechanism for the new Mac book pro with touch bar?

Because the butterfly mechanism is so delicate, any attempt to remove the key cap will end up damaging the key further. I personally would not unless you are a miracle worker. You should be under warranty still considering it is 2018 and this is a 2017 model so take it into an Apple Store and have then look at it.
