Luckily, this is a simple issue to fix. Simply locate something absorbent and put it inside the fob - a paper towl or tissue works well. Use a cotton swab that contains isopropyl for cleaning the circuit board as well as any other components. Let the fob dry out for several days in a dry, warm environment.

If you've just replaced the battery on your key fob but the problem persists, it is possible that the antenna on your key fob is damaged or malfunctioning. The antenna is responsible for transmitting a signal between the key fob and the receiver module. Utilizing an OBDII scanner will aid in identifying the issue by telling you what is wrong with the system. The scanner will ask you for details about your vehicle including the make, model engine type, and VIN number.
Faulty Receiver Module

After 15 minutes, reconnect your battery in reverse order. First, positive and then negative next.
Dirt or water can harm the internal chip of the key fob. If your key's function stopped when it was wet, you need to clean the electronic component with isopropyl ethanol or an electronics cleaner before reinstalling the battery. If the key stopped working after exposure to soapy or salted water, it's likely that the chip is damaged and needs to be replaced.
A defective fuse for the antenna module could also be the reason. It's the fuse that transmits a signal to the vehicle to lock or unlock. Based on the model you have, the fuse is located in one of the many locations like the engine bay, the side of the dashboard, under the rear seat, or in the trunk.
