Dead Coin Battery

The chip is susceptible to moisture and could be permanently damaged. If the key fob doesn't work after replacing the battery, it may be necessary for you to replace the key fob.
Faulty Receiver Module
If your key fob has stopped working after you replaced the battery, but it did not help, or it just stopped working without notice it is possible that your receiver module may have developed a fault. The receiver module is responsible for absorbing the radio frequency signals transmitted by the remote key fob and transform them into electrical commands that are then utilized by other modules in the car.
If the receiver module has developed a fault, it will not respond to any of the commands issued by your remote key fob. In this scenario, a dealer will need to reprogram your key fob and install the new receiver.
The key fob comes with rubber seals that block water from getting into the chip inside. If you submerge the key fob in salty or soapy water it could cause damage to the chip.

Connect the battery in reverse (negative cable to positive first). This will reset all electronic components onboard and bring them back into operation.
Faulty Electronic Chip
The key fob is equipped with a tiny chip which transmits a signal from the key to the receiver module every time the key is used. If the signal isn't in line with the one that the car has stored, the immobilizer will disable and prevent the vehicle starting. However, if the fob isn't functioning and you are unable to reprogram it this could be due a damaged chip.

The best method to do this is by removing the key from its housing and then using a pin needle to connect with each of the clips made of metal. If G28CarKeys are damaged or broken, you will have to replace them in order for the remote control to work. Make sure that the replacement batteries are of the same voltage, size and specification as the original.
