water spilled on keyboard- MacBook Pro

So I accidentally spilled water on my MacBook Pro last night (stupid I know, should have been more careful). Right away I flipped the laptop upside down and cleaned up the water that was spilled onto the keyboard and let it air dry overnight. I turned off right away and just prayed for the best. The next morning I turned it on just to see if it was completely dead or not and to my surprise it turned on! It was working fine for a few minutes like the keyboard and the mouse but then it froze and I had to turn it off. Any ideas on what I should do next? Would I need to replace the whole entire laptop or maybe just the keyboard if it came down to it?
