First, let say I haven't had any reason to remove my case yet. But as you haven't gotten any responses, here's what I have planed to do when I do remove the case. When you put it together you may have noticed that one of the half's had two tabs with notches on them and the other half had two matching holes, that the other half's tabs could slide into and latch with the notches. I would take an old credit card, or something a little slimmer, thickness wise. and gently lift each tab and slide the credit card under each one, to unlatch them and then slide the two half's apart. I don't remember any other parts that had a latch on them, that doesn't mean there isn't another latch somewhere, so check carefully. Hope this helps.
The last time I looked, youtube had plenty of videos on how to put it together, but none on taking it apart, might want to look again before you start.
