Things You'll Need
Instructions
Turn on your TV and Wii console. With your TV displaying your Wii main menu, test your Wii remote that is already synced to your console by pointing your remote at the sensor bar and waving the remote. The hand on your TV screen should respond with your Wii remote movements.
Lift the cover on the front of your Wii console (beneath the "reset" button) to expose the red sync button. The sync button allows your Wii console to recognize a Wii remote that is attempting to sync with the console.
Press the sync button on your console. You only need to press the sync button for a couple of seconds before the Wii sync signal will become active.
Take the Wii remote and turn it on over so that the trigger and battery cover are facing you.
Use your finger to press the release tab up and lift the battery cover from the remote. It is important to lift from the release tab to avoid damaging the battery cover.
Press the red sync button in the lower right corner of your Wii remote beneath the battery holder. Replace the battery cover. Pressing the sync button will make the four player-indicator lights flash, indicating that your console and remote are syncing. Nintendo notes that once the player lights stop blinking, the syncing process is complete.
