Almost 40 years ago, Knox Company took on the challenge of developing a complete rapid entry system specifically designed for firefighters. In 1975, the first Knox-Box® was introduced to the fire service and a unique concept in fire response was born. Knox-Box soon became the fire industry’s high security lock box of choice. In 1981, a section of the Uniform Fire Code mandating the use of rapid entry lock boxes was adopted and remains in use today.

New 2012 Requirement for Key Boxes

Most departments have had at least one property owner question the security of placing their key in a box mounted to the exterior of their building. Knowing the security of the Knox-Box® would be a concern. Knox has taken many steps to make the Knox-Box as impregnable as possible with the majority of the security features designed into the box. We even submit our products to an independent testing lab (UL)* to make sure they meet the security standards we advertise.
