This is a simple fix. Simply find something absorbent and put it inside the fob. A paper towl or tissue can be used. Use a cotton swab soaked in isopropyl to wash the circuit board as well as any other components. Allow the circuit board to air dry in a dry, warm environment for several weeks.

Radio Interference

If a keyfob works correctly, it emits an audio frequency that is absorbed by a receiver module in your car. If the signal is not received the key fob won't work. This could be due weather conditions, objects or other transmitters operating on the same frequency band near your car.

If you've just replaced the battery in your key fob, and the issue persists, it's possible that the antenna on the key fob is damaged or inoperable. The antenna is responsible for transmitting a signal between the key fob and the receiver module. An OBDII scan can aid in diagnosing the issue by telling you exactly what's wrong with the system. The scanner will ask you for information about your vehicle, including the model, make, engine type and VIN number.

Faulty Receiver Module

You can reset the onboard computer if you disconnect the 12 Volt batteries for 15 minutes. This will eliminate any remaining electricity that could be causing problems. Begin by removing your cable from the negative terminal first, followed by the positive terminal. After 15 minutes, connect the battery in reverse order: positive first, negative second.

The internal chip of the key fob may be damaged by dirt or water. If your key quit working after being wet, wipe the electronic component with isopropyl Alcohol or an electronic cleaner prior to reinstalling the battery. If it stopped working after exposure to salty or soapy water the chip may be damaged and must be replaced.

Another possibility is a damaged antenna module fuse that transmits the lock / unlock signal to the vehicle. The fuse may be located in a variety of locations, based on the type of vehicle. For example it could be located under the rear seat, or in the trunk, or the side of the dashboard.
