have you tried the applestore? they replaced the whole topcover/keyboard for me even though it was weeks out of applecare they had problems with them splitting along the front edge and the trackpad had a bit of a bump in it. if you go in there and ask "i would like to fix this is this possible?" you might get lucky.
