Water Damage
You may think that your key fob is lost if you drop it in the water or accidentally wash it. But there's a way to salvage it. When the circuit board inside the fob is exposed to water, it becomes conductor that shorts the components. It also accelerates corrosion and rust.
This is a simple fix. Find something absorbent and place it inside the fob. Paper towl or tissue is ideal. Make use of a cotton swab and isopropyl to clean the circuit board, as well as any other components. Allow the circuit board to air dry in a dry, warm environment for a few weeks.
Replace the battery when the fob has dried out with a new one that is the same dimensions and polarity ('+' (pointing upwards). It isn't easy to open up the fob to get access to the battery, but if have a small flat-head screwdriver at hand, it will slide in easily. Once the fob is assembled and working, it should operate just as normal. If it doesn't, you might need to reprogramme it or replace the receiver module.
Radio Interference
If a keyfob functions properly, it sends out a radio signal that is picked up by a receiver module in your vehicle. If the signal is distorted in any way the key fob won't function as expected. This could be due to factors like weather conditions, objects, or other transmitters operating on the same frequency band close to your vehicle.
This could cause your key fob to not be able to activate the vehicle's systems such as the ignition switch or the security system. It is recommended to replace the battery in your key fob.
Some LED lighting accessories which uses the same frequency as key fobs for remote control may interfere with the signal, preventing it from reaching receiver modules. To avoid interference, the LED light must be switched off or switched to another frequency.
If the problem persists after replacing the battery, the antenna on the key fob might be damaged or malfunctioning. This is significant since the antenna is responsible for transmitting signals from the key fob to the receiver module. An OBDII scan will aid in diagnosing the issue by revealing what's wrong with the system. The scanner will ask you for details about the vehicle you own like the make and model, engine type, and VIN number.
Faulty Receiver Module
The key fob has a receiver module that sends signals for locking and unlocking. All electronic components on board will stop working if this module has a problem. Reprogramming the key fob by an OBDII scan, or replacing it might help.
There are a variety of possible causes which could be due to a dead coin 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 remaining power that could be causing problems. Remove the cable first from the negative terminal, then from the positive terminal. After 15 minutes, reconnect the battery in reverse order: positive first, negative second.
Water or dirt can also cause damage to the internal chip of the key fob. If the key fob you purchased stopped working after being soaked, clean it with isopropyl or electronic cleaner. Then, you can reinstall the battery. If it is not working after exposure to soapy or salty water the chip may be damaged and needs to be replaced.
Another possibility is a faulty antenna module fuse that transmits the signal to lock or unlock to the vehicle. The fuse can be found in several places, depending on the type of vehicle. For example it could be located under the rear seat alhambra key, or in the trunk, or on the side of the dashboard.
