Each entrance to the building is secured after hours by means of a Kastle Systems electric lock. In addition to the pedestrian entrances and the parking garage, both the East and West tower passenger elevators are equipped with Security Entrance Portals at the main lobby. All elevators serving the office towers are equipped with readers and access to individual floors is gained through the use of a Kastle proximity card.

After-hours perimeter building access is through the use of the proximity reader at both the 13th Street and F Street entrances. Visitors or individuals without a Kastle access card who require access into the building after-hours will utilize a hands-free intercom at these locations which rings to the lobby security desk. Once inside the Building, after-hours access to the towers will again require use of the Kastle Security Key. Visitors will be required to check in at the Security Desk located in the Lobby.
