Dead Coin Battery
A dead coin battery is the most common reason of a key fob that isn't locking or unlocking your car. It is likely to show indications before it dies, such as a decreasing range or no power at any time. It is easy to replace it with a new one (CR2025) from the local supermarket. Be aware that defective or defective batteries could cause damage to the key fob. Make sure that the battery you purchase is the same size, specification and voltage as the previous one.
If your fob has been exposed to pure water, such as rainwater or soapy water from the tap, it is likely that corrosion has damaged the electronic chip. You could try cleaning the chip with isopropyl alcohol or an electronic cleaner to test if it helps, but it is likely the chip has been fried.

If your key fob is damaged by dropping it in the pool or by slipping it in the washing machine you might think that it's lost but there's a chance. The issue begins when the circuit board inside the fob is in contact with water - it is a great conductor and cuts off components. It also speeds up corrosion and rust.
Fortunately, this is not difficult to fix. Find something absorbent, and place it inside the fob - paper towl or tissue can be used. Use a cotton swab that contains isopropyl to clean the circuit board, as well as any other components. The fob should dry for a few days in a dry and warm environment.
After the fob has been drained, replace the battery with a new one of the same size and the same polarity ('+' that is pointing upwards). The fob can be difficult to open to access the battery, however should you have a flat-head screwdriver at hand, it should be easy to insert. Once the fob is assembled, it should work just as normal. If it doesn't, then you'll need to reprogram it or replace the receiver module.
Radio Interference
If a key fob is functioning properly, it sends the radio frequency signal which is received by the module inside your car. If the signal is interrupted, your key fob will not function. This may be due to factors like weather conditions, objects, or other transmitters operating in the same frequency range near your vehicle.

Some LED lighting accessories that utilizes the same frequencies as key fobs for remote control may interfere with the signal, preventing it from reaching receiver modules. To avoid interference, the LED lights should be turned off or switched to the opposite frequency.
If the issue is still present after installing a new battery, the antenna of your key fob could be damaged or not functioning properly. The antenna is responsible for transmitting a signal between the key fob and the receiver module. Using an OBDII scanner can assist in diagnosing the problem by telling you what is wrong with the system. The scanner will ask you for information about your specific vehicle like the model and make along with the engine type and VIN number.
Faulty Receiver Module
The key fob contains the receiver module which transmits the signals needed to lock and unlock. All electronic components that are on-board will stop working if this module develops a problem. Reprogramming the key fob using an OBDII scan, or replacing it might help.
There are a few possibilities for the cause of this problem, including a dead coin battery, water damage, or signal interference. It is possible to reset the on-board computer if you disconnect the 12 Volt batteries for 15 mins. This will draw out any remaining electricity 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. First, positive and then negative second.
Water or dirt can also harm the internal chip of the key fob. If your key fob stopped working after being soaked, clean it with isopropyl or electronics cleaner. After that, replace the battery. If it stops working after exposure to salty or soapy water, the chip is probably damaged and needs to be replaced.
Another possibility is an inoperable antenna module fuse that sends the lock or unlock signal to the vehicle. Depending on the model, the fuse is located in a variety of locations, such as the engine bay, side of the dashboard, under the rear seat, or in the trunk.
