Cutting-edge design

When designing Obsidian, Kwikset created the sleekest smart lock available. Obsidian’s style-forward design seamlessly blends with any home’s decor and offers key-free convenience with its capacitive touchscreen.

This style-forward lock is the future of door hardware. Named after the volcanic rock, Obsidian is a visually striking touchscreen that eliminates traditional keyways and opts for a low profile, contemporary design to deliver a stylish, modern smart lock that is secure, innovative and convenient.

Unmatched security

Designed with patented SecureScreen technology to prevent unwanted entry, 128-bit Advanced Encryption Standard (AES) communication, and meets BHMA Grade 2 deadbolt operational and security standards.

SecureScreen keeps you safe

SecureScreen™ provides additional security by employing random digits prior to entering your personal code to prevent fingerprint and code detection on the touchscreen surface.

You’ve got a backup power source

Obsidian features 9V terminals at the bottom of the deadbolt exterior that act as a backup power source in case the batteries run out. Use the 9V battery to quickly power the touchscreen by simply touching the battery prongs to the terminals.

Superior wireless encryption

Obsidian with Home Connect featuring Z-Wave® Plus offers extended wireless range, over-the-air firmware updates, and superior wireless encryption.

Why Isn’t My Obsidian Locking?
There are three possibilities: 1) Obsidian will not lock if your batteries are too low so as to prevent accidentally locking you out. 2) Obsidian may not be locking if the bolt hole on the door frame is not deep enough. Make sure the bolt hole on the door frame is at least 1” deep. 3) Obsidian may not be locking due to a misalignment with the door, door frame, and/or strike. For more information on how to address misalignment, please see the installation guide.
What Do The Different Colored Lights On The Status LED Mean?
Amber indicates locked. Green indicates unlocked. Red indicates low battery.
