Will replacing the upper case fix my problem?

Two days ago, i spilled coffee on my macbook pro. I knew that I had to dry it out, so I tried to open it up to take the parts out, but I couldnt do that because I could not find a screwdriver small enough. So I then spread rice over the keyboard to soak up any moisture that might have gotten underneath. This seemed to work, because afterward my mac turned on and everything was like normal except for the trackpad, which was stuck. So I left the rice on it a few more hours, and after that the trackpad was working much better, though certainly not as well as it did before.

But a few of the keys no longer work on the keyboard, and I was wondering if replacing the upper case will resolve this issue?

Unfortunately, the answer is maybe. Replacing the upper case is not an easy repair. Have a look at this guide if you are thinking of doing it. Read through all the steps so you get an idea of what you are getting into. Whether this would fix the problem depends on how much liquid got into the guts of your machine and how far it went. You won't know that answer until you open the case. If the liquid is only in the keys and track pad you may be in luck and the repair should fix the problems. On the other hand, if you find the logic board and other components covered in sticky residue you may have corrosion happening in the connectors between parts. If you want to give this repair a try read this guide too. If liquid got all the way down into the little connectors, turning on and using your computer before doing a thorough cleaning may be encouraging more corrosion. So if you think you are up for the repair do it sooner rather than later and leave the computer off until you can do the cleaning.
