So a friend spilled some liquids on his new macbook pro 13 5,5.Unibody The keyboard no longer worked, the hd was fried, so he gave it to me and switched to PC's . I replaced the HD, and connected an external keyboard. Luckily nothing else was effected and it powered up. What I find strange is that the backlight still works although NONE of the keys do. The power button and the trackpad still work as well. I have accepted that I have to purchase a costly top case, but could i not just replace the keys? Thanks.
