Faulty Receiver Module
If your key fob stopped working after you replaced the battery, but it did not help, or if it stopped working completely out of the blue it is possible that your receiver module could have developed a fault. The receiver module is responsible for receiving the radio frequency signals transmitted by your remote key fob, and transform them into electrical commands which are then processed by other modules in your car.

Faulty Electronic Chip
The key fob is equipped with a tiny chip which transmits an indication from the key to the receiver module each time the key is used. If the signal doesn't match the one recorded by the car the immobilizer is able to shut off the engine and prevent the vehicle from starting. If the key fob you purchased does not work and you are unable to reprogram it, this could be due to an incompatible microchip.

This can be done by taking the key fob away from its housing and using a needle or pin to touch each metal clip. If the clips are corroded, or damaged, you'll require replacement to allow the remote control to function. Make sure that the replacement batteries have the same size, voltage and specifications as the original.
