Building Access

In order to use your MIT ID card to access specific buildings, rooms, and labs you must first have it activated or reactivated (if your card access has expired). Your access permissions determine which buildings, rooms and labs are accessible to you. To do that, contact the designated Gatekeeper in your department, lab, or center (DLC). Gatekeepers are individuals who serve as liaisons between their DLCs and the Office of Security Operations, the department responsible for activating individual cards.
