The Supra iBox is a convenient way to allow other agents into houses on a particular property. You de-program, or deactivate, a keybox by deleting the instance of the keybox in the Supraweb interface. If you choose, you can later re-program that keybox using the serial number and your shackle code.
Log into Supraweb as an agent. See resources for the website.
Select the “Listing ID” to de-program from the “Showings Dashboard.”
Select “Keybox Settings” from the listing.
Select “Delete Keybox.” This deactivates the Supra iBox.
