Corsair Flag Help

I was just wondering if anyone could help me farm a Lamian Fang Key. I got one from the swamp in Caedarva Mire, but right after I passed through the gate I didn't realize my sneak was down, and got attacked by the undead monster that's guarding the 2nd iron gate. It's really annoying I have to wait until the next Conquest tally. >_< If anyone could help it would be greatly appreciated. Shouted a coupled times in Whitegate/Jeuno, posted on ZAM, no replies. All I need is the key. I can do everything else myself.

Thanks
