Water Damage

If your key fob is wet from dropping it into the pool or throwing it in the wash, you may think it's a goner but there's hope. The issue begins when the circuit board within the fob comes in contact with water - it creates a fantastic conductor, and it shorts out the components. It also accelerates the process of rust and corrosion.

Fortunately, this is not difficult to fix. Simply locate something absorbent and place it inside the fob. Paper towl or tissue work well. Then make use of a cotton swab dipped in isopropyl ethanol to wipe down the circuit board as well as other components to eliminate any battery acid residue or contamination. Allow the circuit board to air dry in a dry, warm environment for a few weeks.

Replace the battery after the fob has dried out with a fresh one that has the same size and the same polarity ('+' (pointing upwards). The fob may be difficult to open to access the battery, however if you keep a flat-head screwdriver in your toolbox it will be simple to insert. Once the fob is assembled, it should work just as normal. If it fails, you may have to re-program it or replace the module.

Radio Interference

If a keyfob functions properly, it sends out a radio signal that is picked up by a receiver module inside your vehicle. If the signal is not received, your key fob won't work. This could be due factors like weather conditions, objects, or other transmitters operating on the same frequency close to your car.

This could cause your key fob to not activate the vehicle's functions such as the ignition switch, or the security system. In this case, it would be best to replace the battery in your key fob.

Some LED lighting accessories that utilizes the same frequencies as a key fob for remote control could interfere with the signal, stopping it from reaching receiver modules. The LED's lighting needs to be switched off or changed to a different frequency in order to be able to avoid interference.

If you have a brand new battery on your key fob but the issue persists, it is possible that the antenna on the key fob is damaged or has stopped working. The antenna is responsible for transmitting a signal between the key fob and the receiver module. A scan of the OBDII can aid in diagnosing the issue by revealing what's wrong with the system. The scanner will ask you for information about your vehicle, including the make, model engine type, and VIN number.

Faulty Receiver Module

The key fob is equipped with a receiver module that transmits the signals for lock and unlock. All electronic components on board will stop working if the receiver module has a problem. Reprogramming the key fob with an OBDII scan, or replacing it can help.

This issue could be caused by a dead coin-cell, water damage or signal interference. You can try resetting the computer on board by disconnecting the battery 12 volts for 15 minutes. This will drain any remaining electrical energy that could be causing issues. Begin by removing your cable from the negative terminal of the battery first, then the positive terminal. After 15 minutes, connect your battery in reverse order. First, positive and then negative, and finally negative.

Dirt and water can cause damage to the internal chip of the key fob. If your key's function stopped after it got wet, clean the electronic component with isopropyl alcohol or an electronics cleaner before installing the battery. If it stopped working after exposure to soapy or salty water the chip may be damaged and should be replaced.

A defective antenna module fuse could be a cause. It is the fuse that transmits an indication to the vehicle to lock or unlock. Depending on the model the fuse can be found in a variety of locations such as the engine bay, on the side of the dashboard, beneath the rear seat, or in the trunk.
