Often wondered that myself.
Mine stopped working last week but opening it with the key seems to have restored the function.

Just opened mine.
At the 'bottom' end, adjacent to the keyring, there is a slot.
Shove a fairly wide bladed screwdriver in and twist, the whole thing just falls apart.

May even buy a new battery now I have conquered that :D

ETA:
Interestingly enough, there are pressure pads for four buttons, wonder what the fourth is for?

Click on the images, then click and click again for full resolution. Should have cropped them, sorry.
Must give the board a blast of contact cleaner. Pity I reassembled it before I thought of that.

The buttons in my C5 remote cracked and I bought a four button remote off Ebay to repair it. I transferred the circuit board (and key) over and it all works as it should.

The extra button is marked with a door symbol with left and right arrows. The buttton which operates the dropglasses also has this symbol and operates the dropglasses as it should. The extra button does nothing.

I suspect that the original use is for the C8, or similar, with electrically operated doors perhaps?

Yeah, I pointed the remote (board) out of the window an shorted the contact pads, all worked but the fourth one.
Could it be a boot release for the saloon?

I don't think so, it would surely have a different picture on the button. As I said both of the auxilliary buttons have the same picture which definitely shows a door, not a tailgate or bootlid.

Query about the C8. Does the exclusive model have two electrically sliding doors? If so, I think that this will be the culprit. Possibly the Peugeot equivalent as well.
