Things They Should Invent: building emergency keys automatically summon the elevator

From an article about emergency response in highrise buildings:

Fire departments are supposed to have access to a universal elevator key, which gives firefighters sole access to elevators without public interference, the study notes. In contrast, only rarely in pre-hospital care systems do paramedics have access to a universal elevator key. “Availability of a universal key seems like a simple intervention, but it has remained unaddressed for decades,” Drennan wrote

In addition to giving keys to paramedics, they should also have a setup where opening the front (or other exterior) door of the building with the universal emergency key summons the elevator to the lobby.

Currently, firefighters can open building doors with a universal emergency key, and take control of elevators with a universal emergency key.  But they still have to make their way to the elevators before they can summon the elevators.

If the elevators started heading for the lobby as soon as emergency personnel enter the building, then the elevators can head to the ground floor as the emergency personnel head across the lobby. This would minimize waiting time, and the precious seconds gained could save more lives.
