I'd take your 'soaked' key, and run it under FRESH water for 5 minutes to get rid of all the salt and then do what HondaGoneRogue says.
The salt will destroy any electronics inside the key if it's not removed completely.
Not much else can go wrong, your key has already been drowned.
I remember back in the day, BMW used to issue a "beach key" which was just made out of plastic... that would be handy.
