Then, use the cotton swab, dipped in isopropyl alcohol and wipe down the circuit board and other components to get rid of any battery acid residue and contamination.

Try resetting the on-board computer by disconnecting the battery 12 volts for 15 minutes. This will flush out any residual electrical energy that could be causing issues. Start by removing the cable from the negative terminal first, then the positive terminal. After 15 minutes, connect your battery in reverse order. First, positive and then negative second.
The internal chip of the key fob could be damaged by water or dirt. If your key has stopped working after getting wet, wash the electronic component with isopropyl Alcohol or an electronic cleaner prior to reinstalling the battery. If your key has stopped working after being exposed to soapy or salted water, it is likely that the chip has become damaged and must be replaced.
Another possibility is a defective antenna module fuse that transmits the lock and unlock signal to the vehicle. The fuse can be found in a variety of locations, based on the model. For instance it could be beneath the rear seat or trunk, or on the side of the dashboard.
