Knox Box Information

The Cambridge Fire Department utilizes Knox-Box® key boxes in many buildings in the city.  Property owners store entrance keys, access cards and floor plans in high-security boxes mounted near their building entrances. Each Knox-Box is keyed to a single master key controlled by the Cambridge Fire Department. With the Knox System, there is no waiting for a property owner to unlock the door in the middle of the night and no forcing the door open to gain entry. The Knox Rapid Entry System reduces response time, property damage and the liability for lost keys.

The application is done online.  To apply or to obtain further information, please visit: www.knoxbox.com

Please note that the 1600 and 3200 series boxes are no longer acceptable in Cambridge due to previous issues with the type of locking system Knox uses.

Once you have received your Knox Box and had it installed, please call our Emergency Communication Center at 617-349-4900 and they will connect you with someone who can send a fire company to open it for insertion of your keys, access cards, floor plans, etc. 

Please contact the Fire Prevention Office at 617-349-4921 or fprev@cambridgefire.org if additional assistance is needed.
