Then you can use an alcohol-soaked cotton swab and a cotton swab isopropyl alcohol and wipe down the circuit board and other components to remove any residue of battery acid and contamination. Let the fob air dry in a dry, warm environment for a few weeks.

Radio Interference
When a key fob functioning properly, it emits a radio frequency signal that is picked up by the receiver module inside your car.

Using an OBDII scanner can assist in diagnosing the problem by revealing what's wrong with the system. The scanner will request details about your vehicle, such as the model and make along with the engine type and VIN number.
Faulty Receiver Module
The key fob is equipped with an electronic receiver that transmits signals to lock and unlock the key fob. If the receiver module fails, all of the on-board electronics will stop working. If this is the case, reprogramming with an OBDII scanner or replacing the key fob could aid.
There are several possible causes for this issue that could be the cause, such as an empty coin battery, water damage or signal interference. You can try resetting the on-board computer by disconnecting the battery 12 volts for 15 minutes. This will drain any remaining electricity that may be causing issues. Remove the cable first from the negative terminal, then from the positive terminal. After 15 minutes, connect the battery in reverse order beginning with positive first, and negative second.
The presence of dirt or water could damage the internal chip of the key fob. If your key fob stopped working after getting wet, clean it with isopropyl or electronics cleaner. Then, you can reinstall the battery. If the key stops working after exposure to soapy or salted water, it is likely that the chip is fried and needs to be replaced.
A faulty antenna module fuse may also be the cause. It's the fuse that sends an indication to the vehicle to lock or unlock. The fuse could be found in a variety of locations, based on the model. For example it could be beneath the rear seat or trunk, or on the side of the dashboard.
