Our Take


Interior View

  • Can easily install onto the existing deadbolt in a short amount of time.
  • SecureScreen patented technology prevents dirty fingerprints lingering on-screen and revealing your pin code.
  • Connected version gives you 30 customizable user codes so family and friends can gain access.
  • Users can plug in a 9V battery for backup power in case of failure.

Exterior Door View


  • No backup key included.
  • Short battery life means they need replaced several times a year.
  • Battery replacement is quite complex and unintuitive, with hard-to-remove battery casing.
  • You cannot remotely add access codes from your smart home hub
  • No standalone app (you use your Z-Wave or Zigbee connected hub like Smarthings or Wink)

Bottom Line

Kwikset have created a stylish alternative to the conventional lock. For those prone to losing keys, the Obsidian Smart Lock provides a sleek alternative for a reasonable price. The patented SecureScreen technology is also a nice touch, making sure that your pin number isn’t revealed by grubby fingerprints.

Thirty customizable user codes make the Kwikset a great tool for multiple occupancy home. The lock’s only real weakness is a short battery life compounded by a hard-to-remove battery casing.

The lock comes with both Zigbee or Z-Wave plus connectivity so you can integrate with smart home hubs. The lock however does not come outfitted with a stand-alone mobile app so you are limited in what you can do like adding access codes remotely from your phone.

If you value style over practicality, however, then the Kwikset Obsidian is as attractive as they come!
