Stuck At Level 2 in Inquisitor's Heartbeat for iOS

Club AppleVis Member

I just purchased The Inquisitor bundle for iOS, and am having fun playing Inquisitor's Heartbeat. However, I appear to be stuck on map 1 of level 2. I'm told there's a locked door in my way, but I can't seem to find the key to unlock it.
While walking around, I'll eventually find something metallic-sounding on the ground, but don't know how to interact with whatever it is, assuming it can be interacted with at all.
Can anyone help me get past this part?

Thanks.

So am I..

I'm playing it for Mac, and am having the exact same problem. I can't seem to figure this level out. Any helpful hints would be greatly appreciated.. Thanks in advance.
