MacBook keyboard buttons not working!!!!?

A few days ago, my cat spilled the cup of tea that I had next to me while I was using the computer. It went all over the keyboard, and the trackpad also got wet. I tried using a hair dryer to see if it would help, and now Ive found that the trackpad works fine, yet there are three keys that do not work. The keys that dont work are the enter, apostrophe, and left bracket keys. Is there a way I can change some lesser keys' function to the enter and apostrophe keys? I am willing to sacrifice the left bracket key, as well astwo other minor keys in order to get back my enter and apostrophe keys. I live in New York City, so its no real problem to go to the Mac store to try and solve this; however, I have many important documents on my computer and I am very unwilling to have them risk losing any of my important files.
