Dead Coin Battery
A dead battery for a coin is the most common reason of a key fob that isn't locking or unlocking your vehicle. It usually shows indications before it dies, such as a decreasing range or no power at all. It is simple to replace with a new one (CR2025) from an area supermarket. Be aware that faulty or unsuitable batteries can damage the key fob. Be sure that the replacement battery is the same size and voltage and that it is the same specifications.
If your device was exposed to clean water such as rain or soapy tap water, it is likely that the chip inside has been damaged due to corrosion. You could clean the chip with isopropyl or electronic cleaners to see if this aids, but the chip is damaged.

Water Damage
You may think your key fob is lost if you drop it in a pool or accidentally wash it. However, there's still a chance. The problem is when the circuit board within the fob comes in contact with water. It makes an excellent conductor and shorts components. It also speeds up the process of corrosion and rust.
This is a simple fix. Simply locate something absorbent and place it inside the fob. A paper towl or tissue work well. Then, use an alcohol-soaked cotton swab and a cotton swab isopropyl alcohol to wipe down the circuit board and other components to get rid of any battery acid residue or contamination. The fob should dry for several days in a warm and dry environment.
Replace the battery once the fob has dried with a fresh one that is the same dimensions and polarity ('+' (pointing upwards). It isn't easy to open the fob to reach the battery, but if you have a small screwdriver with a flat head available, it should be able to slide into easily. After the fob is repaired, it should function in a normal manner. If it doesn't, you may need to reprogram it or replace the receiver module.
Radio Interference
When a keyfob is working properly, it sends out an audio frequency that is absorbed by a receiver module in your vehicle. If the signal is interrupted, your key fob won't function. This can be caused by objects like weather conditions or other transmitters operating on the same frequency near your car.
In this situation, it is best to replace the battery on your key fob. It is best to replace the battery on your key fob.
Some LED lighting accessories which uses the same frequency as a remote control key fob can interfere with the signal, preventing it from reaching receiver modules. The LED light must be turned off or switched to a different frequency to prevent interference.
If the issue is still present after replacing the battery, the antenna on your key fob may be damaged or malfunctioning. The antenna is responsible for transmitting a signal between the key fob and the receiver module. An OBDII scan will help diagnose the problem by revealing what's wrong with the system. The scanner will ask you to provide information about your vehicle including the make, model, engine type and VIN number.
Faulty Receiver Module
The key fob houses an electronic receiver that sends the signals for lock and unlock. If the receiver module develops a fault that causes it to fail, the entire onboard electronics will cease to function. Reprogramming the key fob with an OBDII scan, or replacing it can help.
There are a variety of possible reasons for this problem such as a dead coin battery water damage, or signal interference. You can reset your on-board computer if you disconnect the 12 volt batteries for 15 minutes. This will drain any residual electric current that could cause problems. Start by removing the cable from the negative terminal first, then the positive terminal. After 15 minutes, reconnect the battery in reverse order first: positive, then negative second.
The internal chip in the key fob can also be damaged by dirt or water. If your key stopped working after being wet, wash the electronic component with isopropyl alcohol or an electronic cleaner prior to installing the battery. If the key ceases to function after exposure to soapy or salted water, it's likely that the chip is damaged and must be replaced.
Another possibility is an inoperable antenna module fuse that transmits the lock and unlock signal to the vehicle. The fuse can be located in a variety of places, based on the model. For example it could be located under the rear seat, or in the trunk, or the side of the dashboard.
