Fortunately, this is easy to fix. Find something absorbent to put inside the fob. A tissue or a paper towel will be ideal. Use a cotton swab with isopropyl for cleaning the circuit board and any other components. Allow the circuit board to air dry in a dry, warm environment for several weeks.

This is crucial because the antenna is responsible for transmitting a signal from the key fob to the receiver module. An OBDII scan can aid in diagnosing the issue by revealing exactly what's wrong with the system. The scanner will ask you for details about the vehicle you own, such as the model and make along with the engine type and VIN number.
Faulty Receiver Module
The key fob contains an electronic receiver that sends the signals for locking and unlock. All electronic components on board will stop working if the receiver module becomes inoperable. Reprogramming the keyfob using an OBDII scan or replacing it can help.

Dirt and water can cause damage to the internal chip of the key fob. If your key fob stopped working after being wet, wash it with isopropyl or electronics cleaner. Then, reinstall the battery. If it stopped working after exposure to soapy or salty water the chip may be damaged and must be replaced.
A defective antenna module fuse may also be the cause. This is the fuse that sends an indication to the vehicle to lock or unlock. The fuse can be located in several places, depending on the model. For instance it could be beneath the rear seat, or in the trunk, or the side of the dashboard.
