I had the same problem yesterday! take the pull the contact out for like 4 min or so and it will work. But not the Wii remote (was so for me) So you sync it. First take away the thing that protects the batteri and press the red bottom then will all light were is says how much players it is blinking and open that thing in front of Wii and puch the red bottom. They show you were the sync bottom sits in system setup!
