A desperate cry for help; My alt key has rendered my mac useless!

Question

Hi!
A few weeks ago I spilled a little glass of water on my macbook pro (2010/15") and as a consequence of this the alt key became dysfunctional. Although not mechanically jammed, the macbook seems to be registering a constantly activated alt key. This obviously renders the whole keyboard useless as every button I press results in: •Ω醵üıœπ˙ß∂ƒ¸˛√ªfiö÷≈ç‹›‘’‚ and various secondary functions.
These are solutions i have tried:
Resetting the PRAM and SMC
Disabling the alt the key in system preferences
Removing the alt keys and cleaning the switches
Plain ol' baning away at the keyboard in sheer frustation
I figured that the only solution would be getting the macbook pro repaired, but this is pretty costly here in Denmark; 3000 Dkk = 550 usd = 330 gbp. I never really got around to doing this and have been using a seperate keyboard ever since.
But get this! In the small hours of chirstmas eve/day, I blow out all the christmas candles and go to turn of my macbook pro... there must have been some christmas magic in the air because the "f*•Ω∂é" thing just suddenly worked!!! ;D
But alas, after a single restart im back to square one!
Although extremely frustrated, I'm also a little hopeful that there might be a solution which doesnt involve replacing a whole component just because of one single key... ( I swear I sometimes hear that alt key laughing at me! ;p)
Any advice, suggestions or thoughts would be greatly aprreciated
Merry Christmas/Happy holidays and a happy New Year!
Thanks in adavance

Yea I know, this solution seems unevitable............ But im trying to avoid it
I dont understand how a simple restart reversed the whole thing, i didnt even move the macbook.......?
But then again I don't know what made it work in the first place..
I was afraid that the water caused a short-circuit and that the alt key contact was somehow fried. But the fact that it worked again + the fact that a restart reversed this, might mean this is a software issue or at least an issue that can be resolved by some DIY, ................................or what?
