Thanks, and sorry if this was answered already.
When you slide out the key, there's a little notch visible on the left side of the uncovered area (if you're looking at the bottom of the fob). Stick the point of the key in there and use it as a lever. It will pop the shell part without much force needed. The rubber keys and circuit board may still be covering the battery with the shell removed, but you can pull it right off, uncovering the battery cell.
I just tried it for the first time, it's very simple. Much easier than an old Nissan fob I had that required a precision screwdriver.
