Sioux Falls Fire Rescue requires all buildings to install a key lockbox if the building has:
- Fire sprinklers
- A fire alarm system
- High‑pile combustible storage
These requirements come from the International Fire Code, as adopted by the City of Sioux Falls. Lock boxes are designed to help firefighters get into important areas quickly during an emergency.
Sioux Falls Fire uses lockboxes sold by Knox. A permit is required before ordering a lockbox.
How to order
- Go to knoxbox.com.
- Select “choose your local fire department agency.”
- Search for and select “Sioux Falls Fire Rescue.”
- Choose the box style you need.

- Complete checkout and payment.
Prices vary based on the box style.
Your lockbox must:
- Be within 20 feet of the main entrance.
- Be mounted 6 feet above the ground.
- Within reach is best practice for quick access for the fire department
- Stay in a location approved by Sioux Falls Fire if changes are needed.
You must sign a liability release form before a box can be purchased or keys can be stored. This form is included in the application process on Customer Self Service.
After installation:

Your box must contain keys to:
- Mechanical rooms
- Sprinkler risers
- Fire alarm control panels
- Electrical rooms

A single master key is preferred. If you use multiple keys, color code them:
- Red: Fire protection

If you change a lock, contact Sioux Falls Fire. Staff will update the key in your box.
