If your key fob stopped working after you replaced the battery and it didn't help, or if it stopped working completely without notice the receiver module may have developed an issue.

If the keys are paired but the receiver module has developed a fault, you can try rebooting all the on-board electronics by disconnecting the battery that is 12 volts for a few minutes. Then, reconnect the battery in reverse order (negative cable first, then positive). This will reset the on-board electronic circuit and restore their functionality.
Faulty Electronic Chip
The key fob houses tiny electronic chips that transmits a signal to the receiver module each time the key is used. If the signal does not match the one the car has stored the immobilizer will be disabled and stop the car from starting. If the key fob isn't working and you cannot reprogram it, it could be due to a defective chip.
The chip inside the key fob is not a permanent part of the device and could need to be replaced in order to make it work again.
