Dead Coin Battery

The chip is susceptible to moisture and could be permanently damaged. If the key fob is still not working after replacing the battery, it could be necessary to replace the entire key fob.
Faulty Receiver Module
If your key fob stopped working after you replaced the battery and it did not help, or if it stopped working completely out of the blue, then your receiver module may have developed a fault. The receiver module is responsible for receiving the radio frequency signals transmitted by the remote key fob and converting them into electrical commands that are then used by other modules in your car.
If the receiver module is damaged and is not able to take any commands from your remote key fob. In this case you'll need to visit a dealer for reprogramming of your key fob and a new receiver module.
The key fob has been sealed by rubber to block water from getting into the electronic chip. If you immerse your key fob in soapy water or salty ocean water, the chip inside may be damaged. It is possible to clean the chip by using isopropyl Alcohol to rub it or electronic cleaner, but If your key fob does not work after this, you'll have to buy a new one.
If the keys are paired, but the receiver module is faulty You can try to restart all the electronics in the board by disconnecting the battery that is 12 volts for a few minutes. Then, reconnect the battery in reverse order (negative cable first and then positive). This will reset all electronics onboard and will bring them back into operation.
Faulty Electronic Chip
The key fob is fitted with a small chip that transmits a signal from the key to the receiver module every time the key is used. If the signal doesn't match the one the car has stored the immobilizer is disabled and stop the car from starting. If the key fob you purchased does not function and you are not able to reprogram it, this could be because of a faulty microchip.
The chip inside the key fob could need to be altered in order to make it function properly. The best way to do this is by removing the key from its housing and using a pin or needle to make contact with each of the metal clips that hold it. If the clips are corroded, or broken, you will require replacement to allow the remote control to function. Make sure that any replacement batteries are of the same size, voltage and specifications as the original.
