Well, I made a stupid mistake.

While trying to save a Mii to my default WiiMote (the one I can use without going to home), I think something went wrong. I took the remote over to my friend's house, and when I got home, it is no longer my default remote, so I cannot use the WiiMote, or Home option on either of my WiiMotes now. Help pleez XD

You can take the WiiMote that you want to use as the main one and open up the back of it (where the batteries are , don't pry the controller in half). Then go to where the SD card slot is on the Wii and press and hold the red button on the back of the Remote and the red "sync" button on the Wii at the same time, hold it for about 3 seconds. That should sync your main one.

Then to get the other one online. Press the HOME button on the working remote and go to "Wii Remote Settings". Then Go to "Reconnect" and on both Remotes press the 1 and 2 buttons together at the same time.

Try re-syncing the Wiimote to your Wii at home
