Faulty Receiver Module

If your key fob has stopped working after you replaced the battery and it did not help, or it suddenly stopped working in a sudden manner, then your receiver module might have developed a fault. The receiver module is responsible for absorbing the radio frequency signals that are sent by the remote key fob and convert them into electrical signals that are then used by other modules within the car.

Connect the battery in reverse (negative cable to positive first). This will reset the onboard electronic and restore their functionality.

Faulty electronic chip

The key fob is equipped with a tiny chip that transmits an indication from the key to the receiver module every time the key is used. If the signal received does not match the one stored by the car, the immobilizer will disable the engine and stop the vehicle from starting. If the key fob isn't working and you are unable to reprogram it the issue could be due to a faulty chip.

The chip in the key fob is not an irreplaceable part of the device, and might need to be replaced to make it work again. The best method to do this is to remove the key from its housing and using a pin or needle to get into contact with each of the metal clips that hold it. You'll have to replace them in the event of damage or damaged by corrosion. Make sure the replacement batteries have the same size, voltage, and specification as the original.
