The Billings Fire Department utilizes the Knox program for building access key boxes, padlocks, and gate switches. This is a secure method of providing the fire department instant access to your building or property during an emergency. The fire department is the only agency with a Knox master key. The Knox Company carries numerous types of key boxes including recessed and surface mounted boxes in different colors. If you order a Knox box or Knox item please do not install it until the location is approved by a fire marshal. Please call (406) 657-8423 to schedule an appointment.
