Hi. I have a red Korg Kross 88 key workstation. Someone played the keyboard so often and so hard that 2 of the keys dont work anymore (or not well). Id like to replace them. Do I replace the keys or the whole motherboard? Thank you in advance.

Most likely the contact strips need cleaning or replacement. We have our replacement parts for the Korg Kross 88 listed here:
