Wet/washed key fob.....ruined?

I recently pulled a bonehead move and inadvertently left my one and only key/remote (the dealer only had the one) in with my laundry and didn't find out until it was too late. I've researched pretty extensively and the only information I have been seeing is people who have been lucky and not had any issues after getting the fob wet but the case doesn't appear to be one of the factory, presumably weather sealed, cases. Now it won't work for any functions (lock, unlock, trunk etc). I am relegated to using the key for these functions which isn't a big deal but what I am curious about is to how it is still capable of communicating with the car because I am still able to start the car fine. I also noticed that things such as the temperature settings were all reset, door locks function differently, the turn signal only flashes once instead of the previous 3 times when changing lanes and now the headlights seem to have reverted to DRL. These changes I assume are a result of losing the preferences stored on the remote. My question is whether I have completely bricked the fob or is it salvageable. I do not have a CA setup so I really don't want to have to pay $2-300 for a new fob to simply lock and unlock my doors even though I am already missing the convenience after only a couple days.

Hm. Your are correct as to why the settings reset.

You could try to pop it open, dry it out, and replace the battery. that would be your best bet

The starting still works because the key basically has two separate systems in it. 1 is a coded chip that the car reads as authorization to start. No power required for this function. The second is the remote control functions, which are battery operated.

You might be ok once it thoroughly dries out. Good luck.

Correct.

The actual transponder, which is read when key is inserted, requires no battery power at all. It will not likely be affected by water. Once water comes in contact the full circuitry, data chips, etc. It's basically toast.

OP, Contact a few automotive locksmiths in your area to get a price as well.

Thanks to all who responded but I received a pleasant surprise when I got into my car this evening. I gave the unlock button a habitual "fingers crossed" test and to my surprise, it unlocked all the doors. Sounds like it really did need to fully dry out even though I did take it apart and hit it with a fan for a couple hours after it happened. --took about 4 full days but I suspect the rice trick would have sped the process.
