Signs That a Battery Replacement Is Needed

When your key fob’s battery is losing power, you could notice several warning signs. For example, the buttons to unlock and lock the doors may not respond on the first attempt. If your vehicle is equipped with KEYLESS GO®, the engine may not start quickly by pushing the fob button. Another warning sign is the illumination of an indicator light on the dashboard. Specifically, this warning light will be for the vehicle’s charging system.
