That sucks. I hope you can park it in a garage. Whoever finds the key, all they have to do is drive down the street and hit the lock or the unlock button and see what lights up.
You can program a third key if you can figure out how to take everything out of your console including the bottom tray liner. There is a locator where to put fobs to program them but you need (I think) all keys so the computer knows what number the new key will be. If you don't have at least the first two keys then you can take the fob you have along with the paper bar code tag that was on the ring the salesman gave you and (mine did) said "keep this tag" to the dealer and he can make a new ($200???) key. If the dealer cannot get the as built code which matches he can reset and record all keys, I believe. Also there are several threads concerning keys, use search
We are happy the keys were found in either your pool or the neighbors pool!
Does the key still work after being in the pool?
Yep, wife and I have itags on each set of keys. Had to use that feature once, tracked it down to within 20 feet. Found! We use them in suitcases when we travel. I have heard you can track your own luggage better than the airline can. Inexpensive for a set of four, but I can't remember how much we paid. Amazon.
We have itags on all our vehicle keys. Has saved us more than once
