Request to make it so Kwikset locks codes can be managed through the Xfinity Home system. Even Kwikset locks guides posted on Xfinity's site recommends to manage codes through the online system.
The master code and the secondary codes on Xfinity Home could be setup to sync to the locks which would then remove the need to manually set codes on the locks.
Except from one guide:
"It is recommended that you add and delete all user codes through your Z-Wave or ZigBee control system. If your system does not allow this, the following sections will provide instructions for how to add and delete codes at the lock."
