Faulty Receiver Module
If your key fob stopped working after you replaced the battery and it did not help, or it stopped working completely without notice it is possible that your receiver module may have developed an issue. The receiver module is able to receive radio frequency signals from your remote keyfob, and converts them into electrical commands which are then acted upon by other modules within the car.

If the keys are connected but the receiver module has developed a fault you can try to reboot all the on-board electronics by disconnecting the battery that is 12 volts for a short period of time. Then reconnect the battery in reverse order (negative cable first and then positive). This will reset the onboard electronic circuits and restore their functionality.
Faulty electronic chip
The key fob is equipped with a chip that transmits an indication from the key to the receiver module each time the key is used. If the signal received does not match the one stored by the car the immobilizer is able to shut off the engine and prevent the vehicle from beginning. If the key fob doesn't work and you aren't able to reprogram it, this could be because of an issue with the microchip.

This can be accomplished by taking the key fob out of its housing and using pins or needles to make contact with each metal retaining clip. You'll have to replace them in the event of damage or damaged or corroded. Make sure that the replacement batteries are of the same size, voltage and specifications as the original.
