Stuck Laptop Keyboard Key

I spilled water - ooops! A few days of drying out seemd to fix everything except for one thing - a stuck key. I cannot type the particular letter at this time because I am using the laptop to post ! Just for reference it is located between "tab" and "w" keys and it is between "p" and "r" in the alphabet.

The laptop in kwestion is a Gateway. I cannot remember the specific model number at the moment but it is relatively new at about 7 months. I have removed the key and I will do my best to describe the contsrution of the key:

Below the key are two small plastic cradles that oppose each other. They cross each other to support the key on top of a small rubber diaphragm. Below that assembly is a small sheet of green plastic with a small dark circle directly below the diaphragm.

I have removed the key and removed the plastic pieces and diaphragm. I have gently cleaned it and reassembled it with no luck. Any ideas?

Thanks for any help.
