A month or so ago a splatter of coffee was dropped onto my Macbook pro Unibody. Nothing was affected except the space bar which was shorted. The back light works, the track pad works, the power buttons and all other keys work. I was using the keyboard viewer to operate the machine but I recently started back at school and need the space bar for essays. I took my machine in (no more warrenty) because I thought replacing the keyboard would be more headache than savings and I was quoted 200$. The guy looked at it and said "the entire keyboard assembly is failing". He says the part is 400$ plus labor. Is he full of crap? I was looking on eBay for replacement keyboards (the keys and the membranes etc) and they are only around 50$ or so. Can a dead space bar require the entire keyboard assembly to be replaced? And by keyboard assembly does he mean the entire lower unibody case? Any help would be greatly appreciated.
