To avoid the possibility of a defective coin battery, ensure that you choose a replacement battery that is identical in size, voltage and specifications as the first one. Also, don't use the battery that has been exposed to clean water (rain, clean tap water, or even soda) as this may damage the internal chip. If the key fob does not work you can try reprogramming it using the original key or visit an authorized dealer.
