Your car key remote got wet, what now?

My car key fell into a street drain where it lay there for at least 5 minutes before somebody was able to fish it out. The first thing you need to do is remove the battery and dry out the electronic parts. I used tissue paper to blot out all visible moisture. When everything appeared to be dry, assembled the key back and tried to open the car. Fortunately, it worked. A couple of hours later, it didn't work anymore. When I checked the battery again, there was a little water and it appeared that there was still moisture inside the casing.

The best thing to do here is to find silica gel or a dessicant which you can find inside new shoes or bags. If you can't find any, you can go to a supermarket and buy a pack of rice crackers. I knew One One Rice Crackers had a large pack of dessicant inside. That's the one on the left below. I found the one on the right from a Case Logic bag. Just pack these together with the electronic component of the car key in plastic bag. Seal it and leave it alone for at least 2 days. The objective here is to remove all moisture from the electronics. My key worked again after this. I am still keeping the key with the silica gel bags at least for the week to be sure. Hope this helps.
