keyboard problems 2011 macbook pro 13

[honeybadger]

Woke up this morning and some of my keys, certain letters would not work. Very strange, I checked and updated all my software. Still had problems in pages and keynote. However, when I type in yahoo mail all seem to work??? If anyone has experienced this keyboard issue and solved it please let me know how you did it.
Thanks so much.............

Hi,

I know someone else having similar issues, do you know what keys don't work?

And to answer your other question, yes should be covered under applecare.
