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 battery acid residue or contamination. Allow the circuit board to air dry in a warm, dry environment for a few weeks.

The scanner will ask for details about your vehicle including the make, model engine type, and VIN number.

Faulty Receiver Module

After 15 minutes, connect the battery in reverse order first, positive second.

Water or dirt can also harm the internal chip of the key fob. If your key fob stopped functioning after getting wet, clean it with isopropyl, or an electronics cleaner. After that, replace the battery. If your key has stopped working after being exposed to salted or soapy water, it is likely that the chip has become damaged and requires to be replaced.

A defective antenna module fuse could also be the reason. It is the fuse that sends an electronic signal to the vehicle to lock or unlock.
