My key fob went swimming
Went to our community pool today. Forgot to take my fob out of my bathing suit pocket. Who knows how long it sat at the bottom of the pool, half hour? Anyways, got it out of the water, took it apart and dried everything off. Still worked like a champ.

If that is you in your avatar, then it probably took you forever to get to the bottom of the pool.....with all that buoyancy you got going on up top there.

It does not actually - common myth. If anything it just allows dust and bits of rice to clog up your electronics.. I've heard people are told to do that moreso that they leave it alone while things dry.. best bet for electronics is remove the battery/turn it off, and let the water evaporate!

Avatar buoyancy and rice desiccant aside, there is a reliable way to remove water from a fob if you are unlucky and it fails after a dunking. It uses anhydrous isopropyl alcohol (99% IPA, available from Amazon and some drug stores), not the typical drug or grocery store rubbing alcohol, which is only about 70% IPA. You start by removing the fob battery, and then while the fob is open, shake out as much water as you can. Then squirt 99% IPA into all the nooks and crannies of the fob, and shake it out again. Repeat the IPA step 3 or 4 times, then while it is still open with no battery, set it aside to dry overnight.
This works because IPA and water mix well. So what relatively little water is left after the first shakeout gets absorbed by the IPA, and carried out when you shake out the IPA. The reason you use 99% rather than 70% rubbing alcohol is to give it maximum affinity to absorb water. When you are done with the 3 or 4 squirt and shake IPA cycles, any remaining liquid is IPA with essentially no water, and the IPA evaporates faster and easier than water does. The above procedure saved a fob of my wife’s, and also for at least 3 others who reported back to me that the procedure brought their dead fobs back to life.
