I Thought I Dodged the Bullet
Actually the bullet was hot tea, but I never saw any signs of moisture when I hit my arm against the arm of my easychair spilling a little of the hot stuff on my lap and laptop. A day later the '6','Y', & '=' keys stopped working. No problem! I hardly ever use those keys so Keycaps did the job until the '/' went and I sensed a trend. I went to my local Genius Bar and was told by a sympathetic kid in a blue shirt that they don't carry parts for 'vintage' computers more than five years old. I got my MacBook Pro in 2006.
The instructions were excellent, only I didn't see the one about removing the four screws on the bottom for a while. Once I figured it out it went well. While the case was opened I upgraded the Airport with a used 802.11N card following the excellent I fixit instructions.
Don't drink and drive or keyboard; and if you have to replace a keyboard on a MacBook Pro 1,1 go for the airport upgrade too.
