Classroom Door Locks - Campus Safety

Campus classroom doors include additional hardware that provide the option to lock classrooms from the inside or lock doors automatically when closed. Interior lock hardware has been installed in most general purpose, professional and laboratory classrooms.

The type of locking mechanism installed is dependent upon existing door hardware and operation. In most cases, locking the door from the inside of the classroom is a manual operation. However, in some classrooms the installation of an “Emergency Lockdown Switch” button is required.

Faculty are encouraged to practice locking each door in their classrooms and to make a plan for locking doors quickly if necessary.

In all classrooms, room occupants will be able to unlock and exit doors with one motion egress of the door handle, in compliance with building and fire codes. Building keyholders, UNC Police and other authorized personnel retain the ability to unlock classroom doors from the outside.
