Dead Coin Battery
The most common reason for a key fob that does not lock or unlock your car is due to a dead coin battery. It is likely to show signs before it dies like a lower 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 defective batteries could damage the key fob. Make sure that the replacement battery is the same size and voltage, and has the same specifications.

Water Damage
You may think that your key fob is damaged if you drop it into a pool or accidentally wash it. There's a chance. When the circuit board on the fob is exposed to water, it develops a conductor which shorts the components. It also accelerates the process of corrosion and rust.

seat arona key cover or tissue will be ideal. Use a cotton swab with isopropyl to clean the circuit board, and any other components. Allow the circuit board to air dry in a dry, warm environment for a few weeks.
Replace the battery once the fob has dried out by replacing it with a new one that has the same size and polarity ('+' (pointing upwards). The fob might be difficult to open to get to the battery, but If you have a flat-head screwdriver it will be simple to slide in. Once the fob is assembled, it should work just as normal. If it doesn't, you might need to reprogram it or replace the receiver module.
Radio Interference
If a key-fob is functioning properly, it sends an audio frequency signal that is picked up by the receiver module in your car. If the signal is disrupted the key fob will not work. This could be due to objects, weather conditions, or other transmitters that operate on the same frequency in close proximity to your car.

If you've got a new battery in your key fob and the problem persists, it is likely that the antenna on your key fob is damaged or malfunctioning. The antenna is responsible for transmitting signals between the key fob and the receiver module. Using an OBDII scanner can aid in identifying the issue by revealing what's wrong with the system. The scanner will ask for details about your car, including the make, model and engine type as well as the VIN number.
Faulty Receiver Module
The key fob contains an encoder module that transmits the signals needed to lock and unlock. All electronic components that are on-board will cease functioning if this component has a problem. If this happens, reprogramming with an OBDII scanner or replacing the key fob could assist.
This issue could be caused by a dead coin cell battery or a 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 be causing problems. 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 second.
The internal chip in the key fob can also be damaged by water or dirt. If your key stopped working after it got wet, clean the electronic component with isopropyl ethanol or an electronics cleaner before installing the battery. If it stops working after exposure to soapy or salty water, the chip is probably damaged and should be replaced.
A faulty antenna module fuse may also be the cause. It is the fuse that sends an electronic signal to the vehicle to lock or unlock. The fuse can be located in various places, based on the model. For example it could be located under the rear seat or trunk, or the side of the dashboard.
