There's another picture of the accessory, and it doesn't look fake per say. It's been a while since LV has made anything like that with the kisslock close though, so it's kind of hard (at least for my LV amature eyes) to figure out whether it's real or not.
I have one just like it- I am not an LV expert so I don't know exactly what it would be called, but I bought it years ago. Its a credit card holder/change purse on a key chain- was great through college. LV boutiques still carry it.
