Dead Coin Battery
A dead battery on a coin is the most frequent cause of a key fob not locking or unlocking your car. If it fails you will see a decrease in range or no power. It is easy to replace it with a new (CR2025) one from your local supermarket. Be aware that defective or defective batteries could damage the key fob. Make sure the battery you choose to replace is the same size and voltage and also the same specification.
If your fob was exposed to clean water such as rain or soapy tap water, it is possible that the chip inside has been damaged due to corrosion. You can try cleaning the chip with isopropyl alcohol or an electronic cleaner to check if it works but it is more likely that the chip has been fried.
A new key fob is the most straightforward solution. Most major car dealers sell key fobs and they can be installed by a seasoned mechanic. They can also be purchased on ebay. It is best to work on a surface with good lighting. This makes it easier to work on the small parts inside. You will also be able to avoid placing something in the wrong place. Always keep the key fob in a secured and safe location.
Water Damage
You may think that your key fob is lost if you drop it into the water or accidentally wash it. But there's still hope. If the circuit board inside the fob is exposed to water, it turns into a conductor that shorts out the components. It also speeds up the process of rust and corrosion.
This is an easy solution. Find something absorbent to place inside the fob. A tissue or paper towel will be ideal. Then you can use a cotton swab that has been soaked in isopropyl alcohol and wipe down the circuit board and other components to get rid of any residues of acid from batteries and contamination. Let the fob air dry in a dry, warm environment for a few weeks.
When the fob has dried out then replace the battery with a new one of the same size and polarity ('+' with the upwards direction). The fob may be difficult to open to get to the battery, but should you have a flat-head screwdriver at hand it should be easy to slide in. After the fob is reassembled it should function as normal. If it fails, you may have to re-program it or replace the module.

If a key-fob is functioning properly, it sends the radio frequency signal which is interpreted by the receiver module in your car. If the signal is not received, your key fob won't function. This could be due to objects such as weather conditions, objects, or other transmitters that operate on the same frequency near your car.
In this scenario, it is best to replace the battery on your key fob. 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 can interfere with the signal, preventing it from reaching receiver modules. To avoid interference, the LED lights must be turned off, or to the opposite frequency.
If you've just replaced the battery in your key fob and the problem persists, it is likely that the key fob's antenna is damaged or inoperable. The antenna is responsible for transmitting signals between the key fob and the receiver module. An OBDII scan will aid in diagnosing the issue by revealing exactly what's wrong with the system. The scanner will ask for details about your particular vehicle like the make and model, engine type, and VIN number.
Faulty Receiver Module
The key fob comes with a receiver module which transmits signals to lock and unlock the key fob. The electronic components on the board will stop working if the receiver module develops a problem. Reprogramming the key fob by an OBDII scan or replacing it might help.
This issue can be caused by a dead coin cell battery either from water damage or signal interference. Try resetting the on-board computer by disconnecting the 12 volt battery for 15 minutes. This will flush out any residual power that may be causing issues. Take the cable off first of the negative terminal, then the positive terminal. After 15 minutes, connect your battery in reverse order. First, positive, then negative, and finally negative.
The internal chip of the key fob can be damaged by water or dirt. If your key's function stopped after it got wet, wash the electronic component with isopropyl ethanol or an electronic cleaner prior to installing the battery. If the key ceases to function after being exposed to soapy or salted water, it's likely that the chip has been fried and needs to be replaced.
A damaged antenna module fuse could be a cause. It's the fuse that sends an alert to the vehicle to lock or unlock. Depending on the model the fuse can be located in one of the many locations, such as the engine bay, on the side of the dashboard, under the rear seat, or in the trunk.
