|I don't know if you can pop that key off without ruining the keyboard. I wouldn't try it.|
It could probably be fixed. You'd have to figure out how to remove the keyboard from the laptop, clean up the goo from whatever was spilled on it and if that wasn't enough (which it probably won't be) you'd have to take apart the keyboard and clean it out too.
The other option is to buy a new or used (ebay?) keyboard and replace it.
Either way it's going to be complicated and/or expensive.
Or as I mentioned above you can use an external keyboard. Some later versions of windows have an on-screen keyboard but you list your OS as linux and I don't think linux can do that.
