Replace the battery once the fob has dried by replacing it with a new one with the same dimensions and polarity ('+' (pointing upwards).

If it does not work, you may have to re-program it or replace the module.

Radio Interference

When a keyfob operates properly, it sends out a radio frequency that is received by a receiver module inside your car. If the signal is interrupted the key fob won't function. This could be due to objects like weather conditions or other transmitters that operate at the same frequency as your car.

This could cause your key fob's button to not work the car seat key's systems such as the ignition switch, or the security system. In this instance it is best to replace the battery inside your key fob.

A few LED lights that are aftermarket and utilizes the same frequency as a remote key fob can interfere with the signal and prevent it from reaching the receiver modules. The LED light must be turned off or switched to a different frequency to prevent interference.

If you've got a new battery in your key fob, and the problem persists, it's possible that the antenna of your key fob is damaged or not functioning properly. The antenna is responsible for transmitting signals between the key fob and the receiver module. An OBDII scan will help you identify the issue by revealing exactly what's wrong with the system. The scanner will ask for information about your vehicle including the model, make engine type, and VIN number.

Faulty Receiver Module

You can reset the onboard computer if you disconnect the 12 Volt batteries for 15 minutes. This will draw out any remaining electricity that may cause issues. Remove the cable first from the negative terminal, then from the positive terminal. After 15 minutes, reconnect the battery in reverse order first: positive, then negative second.

Dirt or water can cause damage to the internal chip of the key fob. If your key stopped working after it got wet, wash the electronic component with isopropyl ethanol or an electronics cleaner before installing the battery. If it is not working after exposure to soapy or salty water the chip is likely damaged and must be replaced.

A defective antenna module fuse could also be the reason. It is the fuse that sends a signal to the vehicle to lock or unlock. Based on the model you have, the fuse is located in one of several locations such as the engine bay, the side of the dashboard, beneath the rear seat key transponder programming, or trunk.
