Keyboard failure!

My wireless keyboard had a bit of an accident with some coffee last night and while I thought everything would be ok, the w key no longer seems to work This is bad.
I’m going to have to try to take it apart in a more thorough way and try to clean the contact for that key or something. But this is obviously very sad.

EDIT: I have taken apart my keyboard and found that there seemed to be some residual water stuck between the layers of circuit board (which are basically thin plastic sheets) that are the guts of the keyboard. And lo and behold, a bit of wiping and cleaning and everything seems to be working again. I am very relieved. For a minute I was going to update the entry on wordpress before I remembered that I can do it from MacJournal, which makes life a whole lot easier.
