Dead Coin Battery
A dead battery on a coin is the most common cause of a key fob that isn't locking or unlocking your vehicle. It usually shows signs before it dies like a decrease in range or no power at any time. It is simple to replace it with a brand new (CR2025) one from your local supermarket. Be aware that using the wrong or incompatible batteries could cause damage to your key fob. Make sure that the new battery has the same size, specification and voltage as your old one.

Water Damage
You may think your key fob is ruined if you drop it into a pool or accidentally wash it. However, there's still a chance. The issue begins when the circuit board within the fob comes into contact with water. It is a great conductor and cuts off components. It also speeds up the process of rust and corrosion.
Luckily, this is a simple issue to fix. Find something absorbent to place inside the fob. A tissue or paper towel would be a good choice. Use a cotton swab with isopropyl for cleaning the circuit board as well as any other components. Let the fob air dry in a warm, dry environment for a few weeks.
Replace the battery when the fob is dry with a new one with the same dimensions and the same polarity ('+' (pointing upwards). The fob might be difficult to open to access the battery, however if you keep a flat-head screwdriver it should be easy to insert. Once the fob has been rebuilt, it should operate like a normal. If The KeyLab doesn't, you may require reprogramming it or replace the receiver module.
Radio Interference
If a keyfob functions properly, it broadcasts a radio frequency that is received by a receiver module inside your car. If the signal is interrupted in some way the key fob will not perform as it should.

If the issue is still present after installing a new battery, the antenna of the key fob might be damaged or is malfunctioning. This is since the antenna is responsible for transmitting an indication from the key fob to the receiver module. An OBDII scan will aid in diagnosing the issue by telling you exactly what's wrong with your system. The scanner will ask you for information about your specific vehicle like the make and model, engine type, and VIN number.
Faulty Receiver Module
The key fob comes with a receiver module that sends signals to lock and unlock the key fob. If the receiver module develops a fault that causes it to fail, the entire onboard electronics will cease to function. Reprogramming the key fob using an OBDII scan or replacing it may help.
There are a variety of possible reasons for this problem, including a dead coin battery water damage or signal interference. Try resetting the computer on board by disconnecting the battery 12 volts for 15 minutes. This will drain any remaining electricity that may cause issues. Take the cable off first of the negative terminal, then the positive terminal. After 15 minutes, reconnect the battery in reverse order first: positive, then negative second.
The internal chip inside the key fob may be damaged by dirt or water. If your key quit working after being wet, you need to clean the electronic component with isopropyl alcohol or an electronics cleaner before installing the battery. If your key has stopped working after being exposed to salted or soapy water, it is likely that the chip has become damaged and needs to be replaced.
A damaged antenna module fuse could be a cause. This is the fuse that transmits an alert to the vehicle to lock or unlock. Depending on the model the fuse could be located in one of several locations including the engine bay, the side of the dashboard, beneath the rear seat, or trunk.
