No Power
The Wii remote requires two AA batteries, inserted into the battery compartment, according to the diagram on the remote. Insert new batteries to see if they work, and look at the diagram to ensure you have the batteries inserted correctly.
Sticky Buttons
If liquids and other foreign objects contact the Wii remote, they can cause the buttons to stick. Remove residue from the Wii remote by dipping a clean toothbrush in hot tap water. Shake to remove excess water and then lightly scrub the buttons of the remote, working the bristles into the cracks. Let the remote dry for at least two hours before trying to operate it.
Wii Remote Works Erratically
This problem is likely caused by improper setup of the Wii sensor bar, which recognizes signals from the Wii remote and incorporates them into gameplay on the console. Place the sensor bar as far to the front of the TV top as possible, and use the included sensor bar stand if necessary. Operate the Wii remote from between three and eight feet from the TV for best results.
Remote and Wii Not Synchronized
You must sync the remote with your Wii console the first time you play, and any time after you sync the remote with a different console. Open the battery compartment on the remote and press the red button inside. Next, open the SD card slot on the front of the console and press the red button there.
