The two main functions of the Supra eKEY are located on the bottom half of the screen.
Obtain Key is to retrieve the key or access card from the listing agent's lockbox.
Open Shackle is for the listing agent to remove the shackle from the lockbox to either secure the box to the property, remove it, or relocate it.
Obtaining the Key from the Lockbox | Releasing the Shackle
Note not mentioned in video:
Regarding Opening the Shackle and assigning it to a listing, only do so if the listing is active in MLS.
If the listing is not active and you wish to secure the lockbox to the property, follow the same steps to OPEN SHACKLE, but choose the REASON "None of the above" (bottom quarter of the screen), click DONE. You can add the listing information later.
