Lock Boxes

The Naperville Fire Department uses the Supra Max lock box to gain entry into a building, if necessary.

When installation is made on the outside of your building, please call (630) 305-3768, and a member of the Naperville Fire Department will come out and place your keys (which must be labeled using key label discs) in the box while you are present.
