What the wash does to a fob
A laundry cycle is rough on a fob in three ways: water gets inside, detergent leaves residue on the circuit board, and the heat of a dryer can warp the plastic and components. A short cold wash that you caught early is the most survivable, while a full hot wash and tumble dry is the hardest to come back from.
The good news is the metal emergency blade inside most fobs does not care about the laundry and still opens your door by hand. So even a washed fob usually leaves you a way into the car while you work on the electronics.
Steps to give it the best chance
Pull the fob from the laundry as soon as you find it and open it right away. Take out the battery, separate the halves, and blot everything dry. A gentle rinse with clean fresh water can lift detergent residue off the board, which actually helps before you dry it.
Let all the parts air dry completely for a day or two in a warm, dry spot, never with a hair dryer or oven that could melt the plastic. Then install a fresh battery and test it. If it works, watch it for a few days, since washed fobs sometimes fail again later.
When a new fob makes sense
If the fob is dead after drying, behaves erratically, or it is your only key, replacing it is the dependable move. A mobile locksmith can bring a new fob, cut the blade to your locks, and program it to your car for most makes and models without a dealer trip.
