In a third season story arc, corporate fixer Thorne uses this key to give herself access to a special room in the long-buried military lab under Eureka, where 3 scientists died back in 1939 after experiencing unexpected side effects of the first (secret) nuclear bomb detonations.
Unusual key design done in metal and plastic. Three different versions as created by the propmaker; one clean, one weathered with acrylic insert, and one weathered without insert. The clean key also comes apart to reveal an inner conventional key; this feature was not used in the prop's appearance.
