I bought my X5 about a month ago and the keyless entry wasn't working. Last night, one of my asshole cats knocked the key into their water bowl and nobody in the family noticed it for about half an hour.

Today, I was sitting around inside and pressed the button on the key for no particular reason, and the keyless entry worked! It's the strangest thing... the key doesn't look to have ever been opened, so water should not have gotten inside of it, but none of the buttons were functional previously, and all of them are functional now.

Does anyone have any plausible explanation for this occurrence?
