Left shift key doesn't work

my left 'shift' key stopped working, and it is a nightmare because I use it allot.

I followed all the basic recommendations of previous similar questions:

system preferences>accessibility>keyboard/mouse trackpad as well as the dictation & speech are all in check (no special keys, no slow keys etc).

Opened the keyboard viewer, and the 'shift' is defined properly, when i press the virtual key it responds but the one on the keyboard doesn't (the right one does work).

I pulled out the key and the inside looks intact, with a white silicone thing in the middle and two white frames that hold the key are in place.

Had a little water incident near the computer, but I don't think that any water got to the computer or the keyboard.

Is this an issue of contacts or something? Anyone know how to save it?

Thanks!
