Keyless Go got wet, anything I can do?

Forgot it was in pocket while swimming. Now functions dont work.


Do I just need new battery or is the whole thing toast? Thx

Your key got wet. Take the battery out. Put the key in rice without the back on. Get as much of the board visible as possible and leave the key in rice for 24 hours. Put a new battery in and try it, should work.

Did you go swimming in fresh water or salt water? There are older threads about this out there. Rice is a basic method, silica gel packets are better but not ideal. You'd really want to take the key fob apart, there's threads and youtube videos about how to do it. You'd probably want to use electronic contact cleaner after taking the batteries out and spraying down the whole thing. If it was salt water, the salt will start corrosion and create shorts which the rice/silica gel doesn't really address. Even fresh water will have some minerals that can cause shorts. And if all that doesn't work, you'll have to go to the dealer to get a new key.

It was fresh water. I will try the spraying and rice thing. I have taken apart before for battery already. I will update when complete. Thx

There's also some electronics inside the key fob that doesn't come out when changing the battery. See the videos about changing the key shell, it's a bit more involved than just changing the battery.

Update:


FYI....tried all of the above and the thing still won't work even with new batteries. So going to bite the bullet and get new one.


Wow...$475 for ONE new key with Keeless Go function. Expensive mistake.

Did you try all the dealers in your area? I think the price also varies by dealer. One near me has a coupon for 10% off parts.
