Right-Command Key doesn't work

Well, on my PowerBook G4, there are 2 command-keys (I'm sure that's common).
My right command key doesn't work what-so-ever. I tried using the keyboard viewer and it doesn't turn gray either. Funny thing, but when I press the LEFT one, both cmd keys turn gray.

Well i dont know if its a missing driver or a setting, (maybe even a malfunctioning keyboard?) but if anyone can help I would appreciate it. Thanks.
