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). 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 SEMO, the department responsible for activating individual cards.
