I spilled some beer onto my keyboard and the keys stopped working.
5 - 20 minutes
The keys were not working.
The repair went perfect and I completed my repairs in about 2 hours. My Macbook air works as good as new now, thanks to the repair instructions on your website.
The hardest part of the repair was trying not to strip the tiny screws. Sorry I did not take any photos during the repair process.
