It is also one of the most simple problems to fix since it is usually replaced in just a few minutes. To avoid getting a faulty coin battery, ensure that you use a new battery that has identical in size, voltage and specification as the original one. Do not expose a battery to pure water, such as rain, tap-water that is clean, or even soda, as this could damage the internal chip. If the key fob does not work, try reprogramming the key using an original key or visit an authorized dealer.
