A Knox Box is a secure key vault mounted near the entrance to a building. Knox Boxes are required for all commercial buildings in Edwardsville. Only the fire department has the key to open the Knox Box. When the fire department needs to enter a building in an emergency there are only two choices, they can damage the building by breaking a door or window or they can open the Knox Box, get the key and enter the building quickly and with no damage to expensive doors and windows. Knox has been in business for over 40 years and is trusted by thousands of fire and law enforcement agencies. A Knox Box removes barriers to entry, reduces injuries to responders, and minimizes property damage for building owners.
