If, however, the key fob isn't functioning and you cannot reprogram it the issue could be due a damaged chip. The chip in the key fob isn't permanent to the device and may need to be replaced to make it work again. The best method to do this is by removing the key from its housing and then using a pin or needle to connect with each of the retaining clips made of steel. If the clips are corroded, or damaged, you'll require replacement in order for the remote control to work.
