Luckily, this is simple to fix. Simply locate something absorbent and place it inside the fob. A paper towl or tissue work well. Then apply a cotton swab that has been soaked in isopropyl alcohol to clean the circuit board and other components to clean out any residue of battery acid and contamination.

Radio Interference

The antenna is responsible to transmit a signal between the key fob and the receiver module. A scan of the OBDII can assist in diagnosing the issue by telling you exactly what's wrong with the system. The scanner will ask you for details about the vehicle you own including the model and make of the vehicle, the type of engine, and VIN number.

Faulty Receiver Module

After 15 minutes, you can reconnect your battery in reverse order. First, positive, then negative, and finally negative.

Dirt and water can harm the internal chip of the key fob. If your key stopped working after being wet, you need to clean the electronic component with isopropyl ethanol or an electronics cleaner before reinstalling the battery. If it is not working after exposure to salty or soapy water the chip is likely damaged and needs to be replaced.

A defective antenna module fuse may also be the cause. This is the fuse that transmits an indication to the vehicle to lock or unlock. Based on TheKeyLab have the fuse can be located in one of the many locations like the engine bay, to the left of the dashboard, under the rear seat, or in the trunk.
