« Updating the eKEY - How does it work?

The eKEY app expires daily at midnight - it will then need to connect to the Supra network using cellular service or WiFi to update, which it is programmed to do automatically. If it does not update, it cannot be used to open boxes.

If the eKEY app is opened and has not already updated for the day, it immediately attempts a wireless sync.

If it is unable to sync and update, a RED "X" appears over the Update Key button. By pressing the Update Key button you will be prompted for an Emergency Update or Wireless Update.

What is an iBOX

The Supra keybox works in conjunction with the eKEY. The Keybox holds the keys to the listed property. Any agent with an eKEY, with a confirmed appointment from the listing office/agent, will be able to obtain the keys to show the property to prospective buyers.

Supra Keyboxes are owned by the South Central Wisconsin MLS and loaned to MLS Participants (brokers) based on their listing inventory.

Who can be issued a Keybox?

Keybox checkout is limited to the Participant members (brokers) only. The keybox agreement must be signed by the broker, but can be picked up for the company by anyone the broker designates.

How many are issued?

Keyboxes are disbursed at a rate of 125% of current active, withheld/delayed and pending listings in the following categories: single family, condo, and multi-family.

To check out boxes, call the MLS at 608-240-2800 or email A keybox agreement (CLICK HERE) must be signed by the broker before Keyboxes can be picked up.

What is a Shackle Code?

Each Keybox has its own shackle code. This releases the shackle so that it can be attached to a property (doorknob, railing, etc.) Shackle codes are distributed with each new keybox.

If you add your keyboxes to your eKEY inventory, either on SupraWEB or on your eKEY app, you can keep track of your shackle codes and have them available at your fingertips. The shackle code is also available from the MLS office.

To Release Shackle:

What is the Key Container?
