Hello hello everyone,

So yesterday, I was cleaning my 2012 A1278 MacBook Pro with one of those wet Clorox wipes. I must have grabbed an especially moist one because I think some of the liquid got under the keyboard, and now my p key types ";p" and the semicolon key sometimes controls the volume and mute buttons. It's the strangest thing. In fact, I was locked out of my user account, and finally understood that it was because not all the keys work properly.

At this point I'm not quite sure what to do. I did some research and it looks like at this point my options are to reset PRAM and SMC, or replace the keyboard entirely. I have a feeling that the problem mainly lies in the keyboard, since an external one seems to work absolutely fine. So, I may have goofed on this one.

Does anybody have any advice about how to proceed? Is there a reliable source where one can buy another A1278 keyboard? I have absolutely no problem installing it myself, but I want to get a genuine Apple keyboard for the look and feel, and am dubious about the Chinese Ebay sellers that I found so far. I saw that iFixit sells the keyboard component as well (for a reasonable price of $20), but it looks to be out of stock at the moment.

Would turning over the mac and blowing some compressed air into the keys help at all? Should I take some 99% isopropyl alcohol and wipe down the keyboard again, in hopes that it'll seep in as last time and perhaps clean off the remaining Clorox solution?

I would appreciate any and all help! Thanks so much for your time!!
 
Don’t let anything else seep in there. If you’re confident enough to change your keyboard then it shouldn’t be a problem opening up the MacBook to have a look inside. I’d look for any remaining moisture or any corrosion you might be able to wipe off carefully with alcohol and a q-tip. Of course I don’t need to remind you to unplug the internal battery connection prior to doing any solvent cleaning.

Thanks for the reply! According to guides online, it seems there is no good way of taking out the keyboard in a nondestructive way, so if you do it, you're really committing. Are there any companies that you would recommend buying a new keyboard from? Or things to avoid?
