Fortunately, this is easy to fix. Find something absorbent to place inside the fob. A tissue or a paper towel will be a good choice. Then make use of an alcohol-soaked cotton swab and a cotton swab isopropyl ethanol to wipe down the circuit board as well as other components to eliminate any residue of battery acid and contamination.

Radio Interference

When a key fob working correctly, it sends a radio frequency signal that is interpreted by the receiver module in your car. However, if the signal is damaged in any way your key fob will not function as expected. This could be due to objects, weather conditions or other transmitters operating within the same frequency band close to your car.

This issue can be caused by a dead coin-cell battery, water damage or signal interference. Try resetting the on-board computer by disconnecting the battery 12 volts for 15 minutes. This will drain any residual power that may be causing problems. Begin by removing your cable from the negative terminal of the battery first, followed by the positive terminal. After 15 minutes, reconnect the battery in reverse order beginning with positive first, and negative second.

The internal chip in the key fob can be damaged by dirt or water. If the key fob you purchased stopped working after being soaked, clean it using isopropyl or an electronic cleaner. Then, you can reinstall the battery. If the key stopped working after exposure to soapy or salted water, it is likely that the chip has been damaged and needs to be replaced.

Another possibility is a damaged antenna module fuse that sends the lock or unlock signal to the vehicle. Based on the model you have the fuse can be located in one of several locations including the engine bay, to the left of the dashboard, beneath the rear seat leon key fob replacement, or in the trunk.
