Luckily, this is simple to fix. Find something absorbent to place inside the fob. A tissue or paper towel would work well. Use a cotton swab that contains isopropyl to wash the circuit board, and any other components. Allow the circuit board to air dry in a dry, warm environment for a few weeks.

You can reset the on-board computer by disconnecting the 12 volt batteries for about 15 minutes. This will remove any remaining electricity that could be causing issues. Take the cable off first of the negative terminal, then from the positive terminal. After 15 minutes, connect the battery in reverse order first: positive, then negative second.

Dirt and water can damage the internal chip of the key fob. If your key's function stopped after getting wet, wash the electronic component with isopropyl alcohol or an electronics cleaner before installing the battery. If it is not working after exposure to salty or soapy water the chip could be fried and will need to be replaced.

Another possibility is a damaged antenna module fuse that transmits the lock / unlock signal to the vehicle. Depending on the model, the fuse is located in a variety of locations, such as the engine bay, the side of the dashboard, under the rear seat, or trunk.
