The decision of whether or not the key fob needs to be reprogrammed depends on the condition of the battery. If your key fob doesn't work after replacing the batteries, the terminal contacts of the battery are likely damaged. You can also deprogram your electronic key fob by pressing the buttons too often when you're out of range or disconnecting your car's battery.

If the key fob does not work after replacing the battery you must have it reprogrammed for your vehicle. It will depend on your specific car model, but you'll typically need to lock and unlock the doors manually.
