Dear tonycolla,
Welcome to the forums and I can confirm after taking this laptop apart a few times that if you take your time and separate the screws you can do this without instructions.
I can however also confirm that you need to remove the back of the laptop, the battery, the heatsink for the GPU and CPU, everything connected to the mainboard including the monitor connectors, the hard drive and a few other connections to remove the motherboard so you can change out this keyboard.
It is unfortunately one of the hardest components to change besides the mouse pad and it will take patience, time and organization not to lose the screws and to put everything back as it should be.

Finally got around to changing my keyboard, working great now. Thanks for the help.
Were you able to find breakdown instructions or did you feel your way along? I need to do this and I'm a bit nervous without having breakdown instructions!
