Only some keys working after I spilled water through the keyboard.

Recently spilled some water on my Mac, through the keyboard. At first none of the keys worked, but after i let it dry abit only the keys A to L and the "mouseclicker" under the touchpad is not functioning. Since the problem seems to be only to some of the keys, and the rest of the mac seems to be working normally. What could be the problem, and how do i fix it? Found some related questions and answers but it didn't quite fit my problem, so hope i can get an accurate solution
