This may present an opportunity to do just that!
, the missing keys unlock perimeter fences and key entry points. Overall, the keys could open around 100 perimeter gates, 150 other gates, and an “unknown amount” of doors, elevators, and washroom
I often see 'construction' gates with a guard resting nearby, guessing? They padlock them during off hours and are a temporary workaround?
That said, with 12 sq miles, probably MANY access points with padlocks.
