Turn on wii. Press A to main wii menu (with another working remote). If no remote is yet synced wii should prompt you to do so at this point, either way continue to next step.
Press and hold red sync button (inside little door under power button) for 3 seconds.
Then press red sync button on the remote (under battery door). lights will flash and one will stay lit to show you which player that remote has become.
**You can sync your remotes to other game consoles, however each time you change consoles that you are playing you will need to re sync your remote. ( not all remotes just the ones played on another console)
Happy gaming. -B
