Hi, how much keyboard replacement for Macbook pro late 2011.

MacBook Pro late 2011
2.8Gz Core i7, 4GB RAM, 750GB HDD, Superdrive.
Keybord faulty.
No, just check it myself.

My macbook suddenly cannot turn on using power button. Try to remove the battery and plug the power cord without battery can turn it on. Just found out that the problem come from keyboard as power button is a part of the keyboard and most of the key behave weirdly when pressed. now, i need to used usb or bluetooth keyboard if i want to use my mac.

Do you provide the service to replace just the keyboard & not the whole top part? Thank you
