Broken Keyboard on Y580, where can I find replacements?

Hi there,

I bought an ideapad y580 over the summer but idiotically managed to spill a small amount of water on the keyboard. Initially, it (and the touchpad) didn't work at all but after disassembling the computer and unplugging and repluggling back in the ribbon fixed the touchpad but now when I type on the keyboard sometimes it types more than one thing, for example 'e' gives me 'eu' and 'y' manages to "press" control+f+y. I figure it's just easier to pay for a new board but only ones Ive been able to find are on ebay which I'm not sure I trust very much. Any official replacement store? Or, alternatively, if anyone knows of a program that would be able to say "oh this combination of 'e' and 'u' pressed so close together means it's just an 'e'" so it basically remaps the keyboard or something.

Thanks for the help! I think everyone knows the specs but here are my variables:
1080p screen
120gb SSD in SATA III bay and 500gb stock HDD in optical port
Windows 7 Ultimate 64 bit

eBay. They have em for days and they are cheap enough.
