Water Damage
If your fob's key gets submerged after dropping it into the pool or by slipping it in the washing machine you might think that it's gone but there's hope. When the circuit board inside the fob is exposed to water, it transforms into an electrical conductor, which shorts the components. It also speeds up corrosion and rust.
This is a simple fix. Simply find something absorbent and place it inside the fob - a paper towl or tissue works well. Use a cotton swab with isopropyl to cleanse the circuit board, and any other components. The fob should dry for some time in a dry and warm environment.
Replace the battery once the fob has dried by replacing it with a new one with the same size and polarity ('+' (pointing upwards). The fob may be difficult to open to get to the battery, but when you have a flat head screwdriver it will be a breeze to insert. After the fob is repaired, it should function just as normal. If it doesn't, you may require reprogramming it or replace the receiver module.
Radio Interference
If a key-fob is functioning properly, it emits a radio frequency signal that is interpreted by the receiver module inside your car. If the signal is damaged in some way your key fob will not work properly. This could be caused by things, weather conditions or other transmitters operating within the same frequency band near your car.
This can cause your key fob to not activate the car's systems like the ignition switch or security system. It is recommended to replace your key fob's battery.
Some LED lighting accessories which uses the same frequency as key fobs for remote control could interfere with the signal, stopping it from reaching receiver modules. To avoid interference, the lighting must be turned off, or switched to another frequency.
If the issue persists after replacing the battery, the antenna on your key fob may be damaged or not functioning properly. The antenna is responsible to transmit a signal between the key fob and the receiver module. An OBDII scan will assist in diagnosing the issue by revealing what's wrong with the system. The scanner will ask you for details about your car including the make, model engine type, and VIN number.
Faulty Receiver Module
The key fob is equipped with the receiver module which transmits the signals for lock and unlock. The electronic components on the board will stop working if the receiver module is affected by a malfunction. If this is the case Reprogramming using an OBDII scanner or replacing the key fob may help.
This problem could be caused by a dead coin-cell or water damage, or signal interference. You can reset the on-board computer if you disconnect the 12 Volt batteries for 15 mins. This will drain any remaining electrical energy that could be causing problems. Remove the cable first from the negative terminal, then the positive terminal. After 15 minutes, reconnect the battery in reverse order beginning with positive first, and negative second.
Dirt and water can affect the internal chip inside the key fob. If your key has stopped working after it got wet, wipe the electronic component using isopropyl alcohol or an electronics cleaner before installing the battery. If it stopped working after exposure to soapy or salty water the chip is likely damaged and must be replaced.
A defective fuse for the antenna module could also be the cause. It's the fuse that sends an electronic signal to the vehicle to lock or unlock. Depending on the model the fuse can be found in one of several locations, such as the engine bay, the side of the dashboard, under the rear seat, or in the trunk.
