If you need to sync up all of the remotes, you can possibly run into an issue where the remotes will not sync. However, some of the other Wii remotes to keep their sync. In this case it has to do with the time-out during the one-time sync mode.
Here is how you fix the issue:
When syncing or re-syncing Wii Remotes with One Time Mode, if you wait between syncing each Wii Remote, each new Wii Remote you to sync will take longer. This can cause one or more Wii Remotes not to sync at all if too much time has passed.
To avoid this, quickly press the 1 and 2 Buttons on each Wii Remote during the sync process, in the order in which you want to the player numbers to be assigned (1 through 4). Too long of a pause can take the sync longer, or prevent it from syncing all Wii Remotes.
