A dead battery for a coin is the most frequent cause of a key fob that isn't locking or unlocking the doors. It is also the simplest to repair as it can be replaced in only several minutes. To avoid getting a faulty coin battery, always choose a replacement battery that has identical in size, voltage and specification as the original one.
