I spilled soda on the keyboard, but I found a replacement one online.

I purchased the machine the first week after this model was available for sale, and within a week I had spilled soda-pop on it. To this day I haven’t managed to damage it further, but I am unable to find a service center that will fix the backlight. The backlight still turns on and off, but at a very limited range of brightness, as well as uneven lighting across the keyboard, with certain keys being stuck on maximum brightness.

I have had the computer serviced a couple of times by Apple, but the keys seem to be all-around sticky from time to time anyways. Apple was unwilling to repair the keyboard’s backlight without doing a motherboard replacement as well. I am unwilling to pay that much to fix the backlight especially if the motherboard works fine. (And I would have to reinstall my bootcamp windows partition if they replace my internal SSD)

However, I found a replacement keyboard on amazon. So my question’s are how would I go about installing this, and does this contain the parts necessary to fix the backlight? Thanks in advance to whoever answers.
