Dead Coin Battery
A dead coin battery is the most typical cause of a key fob not locking or unlocking your car. It will usually show warning signs prior to dying like a lower range or no power at any time. It is easy to replace it with a fresh one (CR2025) from an area supermarket. Be aware that using the wrong or non-compatible batteries can cause damage to your key fob. Make sure that the new battery is identical in size, specifications and voltage as your old one.
If your device was exposed to clean water, such as rain or soapy tap water it is likely that the chip inside has been damaged by corrosion. You can clean the chip with isopropyl or electronic cleaners to see if that aids, but the chip is fried.

Water Damage
It's possible to think that your fob is damaged if you drop it into the water or accidentally wash it. There's a chance. The problem begins when the circuit board inside the fob comes into contact with water - it creates a fantastic conductor and shorts out components. It also speeds up the process of corrosion and rust.
Luckily, this is a simple issue to fix. Simply find something absorbent and put it inside the fob - paper towl or tissue is ideal. Make use of a cotton swab and isopropyl for cleaning the circuit board, as well as 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 may be difficult to open in order to access the battery, however If you have a flat-head screwdriver at hand it will be a breeze to insert. After the fob is put back together, it should work as normal. If it doesn't work, you'll need to reprogramme it or replace the receiver module.
Radio Interference
When a key fob functioning correctly, it transmits an audio frequency signal that is received by the receiver module inside your car. If the signal is damaged in some way your key fob will not work properly. This could be due to objects such as weather conditions, objects, or other transmitters that operate at the same frequency as your car.
In this scenario it is recommended to replace the battery on your key fob. In this case it is recommended to replace the battery on your key fob.
A few LED lighting products that utilizes the same frequency as a remote control key fob may interfere with the signal, preventing it from reaching receiver modules. To avoid interference, the LED lights must be turned off or switched to another frequency.
If you've got a new battery on your key fob but the issue persists, it is likely that the antenna of your key fob is damaged or has stopped working. The antenna is responsible for transmitting signals between the key fob and the receiver module. An OBDII scanner can help diagnose this issue by telling you what is wrong with the system. The scanner will ask to provide information about your vehicle, including the model, make, engine type and VIN number.
Faulty Receiver Module
The key fob houses an encoder module that transmits the signals for locking and unlock. All electronic components that are on-board will cease functioning if this component becomes inoperable. If this is the case, reprogramming with an OBDII scanner or replacing the key fob could help.
This issue can be caused by a dead coin cell battery, water damage or signal interference. Try resetting the on-board computer by disconnecting the 12 volt battery for 15 minutes. This will remove any remaining electrical energy that could cause issues. Take the cable off first of the negative terminal, then from the positive terminal. After 15 minutes, connect your battery in reverse order. First, positive and then negative the next.
The internal chip in the key fob can be damaged by water or dirt. If your key quit working when it was wet, you need to clean the electronic component using isopropyl alcohol or an electronics cleaner before installing the battery. If it stopped working after exposure to soapy or salty water the chip could be fried and will need to be replaced.
Another possibility is a defective antenna module fuse that transmits the signal to lock or unlock to the vehicle. The fuse may be located in a variety of places, based on the type of vehicle. For G28 , it could be under the rear seat or trunk, or the side of the dashboard.
