Kwikset Obsidian—Battery Replacement

When it is time to replace the battery in your smart door lock, you will see an alert on your system panel, as well as a notification in the Brinks Home™ Mobile App.

The Kwikset Obsidian keyless smart door lock requires 4 AA batteries, which can be purchased at your local hardware, mass retailer, or battery store. You may also order these online here or at your preferred online retailer.


Backup Power Instructions:

If the 4 AA batteries are too low to operate the lock, use a 9-Volt Alkaline battery to temporarily power the touchscreen.

  1. Make sure both terminals on the 9-Volt battery touch the terminals at the bottom of the touchscreen.
  2. Hold the 9-Volt in place while entering your user code to unlock the door.
