We haven't played wii in a while because the batteries were dead. we changed the batteries and now the remote controls won't work. the lights come on but nothing happens.

A lot of people have trouble synchronizing their Wii Remotes to their Wii console. I have written a short tutorial on how to do this.<br /><br />Figure out which scenario is similar to yours and proceed with the solution-<br /><br />1) When you turn on the Wii console and press any button on the remote no lights light up at all. This is because the remote is dead, you must replace the batteries in the battery compartment on the underside of the remote. If the controller is using a charge pack you need to put the controller on its charger.<br /><br />2) When you turn on the Wii console and press a button on the controller all four lights blink a couple times then turn off. This means the controller is not synchronized. If your controller has ever been previously synchronized all you need to do is press the 1 and 2 buttons at the same time and it will sync up.<br /><br />3) If option 2 doesn't work then this means you are preforming a first time synchronization with the remote. While the Wii console is turned on you should open the little compartment that is just below the disc tray. Then you should press the little red button. After pressing the red button you should open your Wii Remotes battery compartment, remove the batteries and press a similar little red button inside of the compartment. Put the batteries back into the controller and the controller should be synchronized! <br /><br />If none of these solutions are working then the problem is a technical issue with either the Wii remote or the Wii system, you should contact technical support for more information.<br /><br />I hope this helped with the synchronization of Wii Remotes!<br />
