Well I did the keyboard replacement with ease. I was fooling around back and forth with other things but my best guess is that it took less than one hour total. Yes I did make a one drop blood sacrifice. Be careful when reaching under that keyboard as there are some sharp metal edges. One thing I did do was write the step numbers in scraps of paper and placed the screws on those. In reality it is probably not needed.
These instructions are some of the clearest, easy to follow guides I have ever run across. Thanks Ifixit!
The only thing that spooked me was that I removed a battery that was near fully charged. When I put all back together it showed a 0% battery and the mac would shut down immediately after unhooking the charger. Now about a couple hours later it is showing over 75%. I am guessing maybe the removal of the battery resets things inside the mac and it thinks the battery is dead? No idea why but it seems to be charging up. Just a mystery that bugs me.
