macbook keyboard not working

[7mazrik]

Hi
I am not sure what happened but it seems my two year old child might have spilled something on my macbook. The keyboard stopped working, and when I pressed a key the letter "Z" got stuck"/
I purchased a used "topcase" from ebay, installed it and i am still experiencing the same phenomonon, although other letters can type normally.
My gut instinct is that there is something else wrong ""deeper to the keyboard"
Does any body have any ideas, where can I get replacement parts for a deeper "pathology".

Thanks

Your best bet would be to take it into an Apple store and ask them what the problem is. You can then either ask them to fix it, or you will know the problem yourself and be able to buy parts.
