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 period.

The Kwikset Obsidian keyless smart door lock requires 4 AA batteries, which can be purchased from Indiana Alarm, local hardware store, mass retailer, or battery store.

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.
