The Registration Key is a unique key, in the format XXXX-XXXX-XXXX, that can be found on the Registration Sheet.
For R Series models, it is also located on the Router's enclosure.
Disassociating the Sevio Router from the Realm allows you to reuse the Registration Key to associate it with another Realm.
In case of loss, the registration sheet can be downloaded from the Devices section of the Sevio Portal > Parameters Submenu.
