Dry It in the Sun or In a Hair Dryer

Very much like regular laundry, hanging or spreading it out to sit in the sun for a period of time a day, based on the weather, is among the effective techniques to dry everything out. On a long hot afternoon, only a few hours would indeed be required.

Another effective and much quicker method to cure it is to use a blow dryer. If the key cannot be completely pulled separately, try attempting it several times over a day while using moderate heat for a couple of moments. The more time you give it to cure, the more likely it is to function properly once again.


So what do I do if I Washed My Car Keys, and Now It Won’t Start? Go as far as you can to dry up the key fob because a wet key could cause many problems and expenses. Soak it in the rice, or dismantle and dry it. And make sure to completely dry up the key before using it.
