Few more items

Back to spot got the costume jewelry. This key item and possible watch fob? It's interesting like it's melted lead attached to the chain

Is that perhaps a metal strip wrapped around the "key"?

If so that was how some cans were opened way back when, the "key" end had a slot on the end and on the can there was a little tap of metal on a "strip" at the edge/top of the can, that tab would go into the slot and then you twist the key and the metal strip would separate from the can as it wrapped around the key until you went all the way around the can and thus removed the top of the can.

Here's photo of Crisco can from back in the day with the "key" attached to the top of the can, if you look closely you can sorta see the "tab" that inserts into the key above the C in Crisco.

Just a larger version of a sardine key basically?

Exactly, they were used on all kinds of cans and other metal containers, not just food items, anything they would need to seal up until use.

Actually it's a little bit different than a sardine can/key but sorta the same idea only with a sardine can the key removes the top cover of the can/tin, but not the rim, most all others work similarly to the following video, which is what I think your key maybe from.
