The Wii Remote is held together by four specially designed screws. And by specially designed, I mean designed not to be opened. You need a special screw driver. Fortunately, Bill Detwiler had already tracked one down for the original Wii gallery.
In addition to the screws, there are two clips near the IR end of the remote. These clips require some force to get open, but not too much.
