Knox Key Box Information

Key Boxes (Knox® Rapid Access)

Why it matters: Key boxes provide first responders rapid, damage‑free entry during emergencies when doors, gates, or secured areas would otherwise delay access. Under OFC §506, the fire code official may require a key box where access is restricted or immediate entry is necessary for life‑safety or firefighting operations.

MCFD1 uses Knox® Rapid Access Solutions. The Knox program is the standard used by thousands of agencies nationally; its products are UL 1037 listed and designed to minimize property damage and responder injury during urgent entries.

Note on code editions: Oregon adopted the 2025 OFC effective October 1, 2025 with a 180‑day phase‑in during which the 2022 OFC remains valid for plan review through March 31, 2026; references on this page reflect §506 in Chapter 5 of the OFC (consistent with IFC 2021).

 

When is a key box required?

Under OFC §506, the Fire Marshal is authorized to require a key box when:

  •  Access is restricted due to secured openings or immediate access is necessary for life‑safety/firefighting.
  • Sites with gates or barriers must have an approved means of emergency
    operation (e.g., Knox key switches, padlocks).
  • In practice across Oregon, many jurisdictions require key boxes for buildings with fire alarm or sprinkler systems, elevators, hazardous materials, or secured gates—MCFD1 applies the same OFC authority case‑by‑case.

 

If you’re unsure whether your occupancy needs a key box, contact MCFD1’s Fire Prevention Division at (503) 588-6533. We’ll determine applicability under OFC §506 based on your site conditions.

  3. Choose your model (3200 for most single‑tenant occupancies; 4400 for larger/multi‑tenant).      
  4. Use the installation address (not just the shipping address) during checkout. 
  5. After installation, contact MCFD1 to schedule a lock‑in of keys and a final placement check. 

Installation Guidelines

  • Mounting height: Suggested minimum 6 ft above finished grade to deter tampering and aid visibility.
  • Location: Near the primary entrance or recognized fire department entry/control point (e.g., by the fire alarm panel or sprinkler riser).
  • Surface/recessed mounting: Follow Knox installation instructions; mount to a solid wall/beam, use grade 5/8 hardware, keep the bottom un‑caulked for drainage, and avoid mounting face‑down under overhangs.
  • Tamper switch (optional): If purchased, have a qualified installer integrate into your alarm system per manufacturer instructions.

What to Place Inside

Stock the box with labeled, up‑to‑date access items so crews can reach all areas quickly:

  • Exterior and interior master keys (including tenant, mechanical, electrical, sprinkler riser, and alarm rooms) and elevator keys where present.
  • Access cards/codes for doors, gates, and secure areas.

 

Use key tags to identify the room or function of each key.

Maintenance and Updates

If you re‑key locks or change access credentials, notify the Fire Marshal immediately and provide updated keys/codes—OFC §506 requires the premise key be secured in the box.

Periodically verify contents and labeling, and ensure the box remains visible and unobstructed.

Security & Program Controls

Only authorized MCFD1 personnel possess the master key to open Knox systems in our jurisdiction; keys are controlled on apparatus and may be electronically retained/audited per Knox KeySecure practices.

Knox products are UL 1037 listed and designed to provide secure, rapid access while protecting your property from unnecessary forced entry.
