spilled a fruit smoothie on my keyboard, what do I do?

yesterday, i was using my VAIO computer while eating breakfast( i had to finish some animations ) and while drinking a homemade smoothie I made, I accidentally spilled more than half of it onto my keyboard. I had slept like nothing the night before, soo I was quite tired and did nothing about it, and took a nap.

today I turned on my computer and searched for a song to listen while animating when I noticed: neither the A,Q,J, and the back space weren't working at all. i don't want to spend all my money just to fix them. is there anything I can do about this? or is my computer doomed?
