Dead Coin Battery
The most common reason for a key fob that does not be able to lock or unlock your car is a dead coin battery. It is likely to show warning signs prior to dying such as a decreased range or no power at any time. It is easy to replace it with a new (CR2025) one at your local grocery store. Be aware that using the wrong or incompatible batteries could damage your key fob. Make sure that the new battery has the same size, specification and voltage as your old one.
If your fob was exposed to clean water like rain or soapy tap water it is likely that the electronic chip inside has been damaged by corrosion. You can clean the chip with isopropyl or electronic cleaners to see if it helps, but it's likely that the chip is fried.
A new key fob is a simple solution. They are available at most major dealerships and can be fitted by an experienced mechanic. They can also be bought on the internet from sites like ebay. It is best to work on a surface that has good lighting. It is easier to work with small parts. This will also allow you to avoid putting things back in the wrong place. Always keep the key fob in a secured and safe space.
Water Damage
You may think that your key fob is lost if you drop it into the pool or accidentally wash it. However, there's still a chance. When the circuit board inside the fob is exposed to water, it develops a conductor which shorts the components. It also accelerates the process of rust and corrosion.
This is an easy solution. Find something absorbent to put inside the fob. A paper towel or tissue will be ideal. Use a cotton swab with isopropyl to cleanse the circuit board and any other components. The fob should dry for some time in a warm and dry environment.
When the fob has been drained then replace the battery with a new one of the same size and the same polarity ('+' pointing upwards). It can be difficult to open up the fob to get access to the battery, but if have a small screwdriver with a flat head handy it should slide in easily. After the fob has been reassembled it should function like normal. If it doesn't work, you'll require reprogramming it or replace the receiver module.

If a key fob is functioning properly, it emits the radio frequency signal which is received by the receiver module inside your car. If the signal is disrupted in some way, your key fob won't function as expected. This could be due to objects like weather conditions or other transmitters that operate on the same frequency near your car.
This can cause your key fob's button to not work the vehicle's systems like the ignition switch or the security system. In this scenario, it would be best to replace the battery in your key fob.
Some LED lighting aftermarket that utilizes the same frequency as a key fob for remote control could interfere with the signal, preventing it from reaching receiver modules. To avoid interference, the LED light must be turned off, or switched to a different frequency.
If the issue persists after installing a new battery, the antenna of your key fob could be damaged or malfunctioning. The antenna is responsible for transmitting signals between the key fob and the receiver module. An OBDII scan can assist in diagnosing the issue by revealing exactly what's wrong with the system. The scanner will ask for information about your vehicle, including the make, model engine type, VIN number.
Faulty Receiver Module
The key fob comes with a receiver module that sends signals to lock and unlock the key fob. All electronic components on board will cease functioning if this component has a problem. Reprogramming the key fob by an OBDII scan or replacing it can help.
There are a number of possible reasons for this problem such as a dead coin battery water damage, or signal interference. You can reset the onboard computer if you disconnect the 12 Volt batteries for 15 minutes. This will eliminate any remaining electrical energy that could be causing issues. Take the cable off first of the negative terminal, then from the positive terminal. After 15 minutes, reconnect your battery in reverse order. Positive first, then negative the next.
The internal chip in the key fob can be damaged by dirt or water. If your key has stopped working after being wet, you need to clean the electronic component with isopropyl Alcohol or an electronic cleaner prior to reinstalling the battery. If the key ceases to function after exposure to salted or soapy water, it's likely that the chip has become damaged and requires to be replaced.
A defective fuse for the antenna module could be a cause. It is the fuse that sends a signal 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, the side of the dashboard, beneath the rear seat, or trunk.
