Bottom Line
Choose the Kwikset Obsidian for a clean, keywayless PIN lock that fits modern doors; Skip it if you want built-in Wi-Fi/Bluetooth or richer app-based guest access without depending on a Z-Wave hub.
Best for
Homes that want a clean, modern, fully keyless look and mostly use PINs, especially if they already run a Z-Wave hub (SmartThings, Wink, Control4) for routines and remote status checks.
Not for
Anyone who insists on a physical key backup, wants HomeKit/Matter-first support or built-in Wi-Fi/Bluetooth, or needs lots of time-limited guest codes that are easy to create and manage from a dedicated app.
Verdict
Kwikset Obsidian is a minimalist touchscreen deadbolt that prioritizes clean design and simple PIN entry, and reviewers generally found its locking reliable with a handy auto-relock option and SecureScreen protection. The catch is that the smart experience is ecosystem-dependent: remote control, voice assistants, and activity history typically require a Z-Wave hub, and some platforms still make code management awkward. Another tradeoff is backup and upkeep: there is no physical key, so batteries and the 9V jump terminals matter, and reported battery life varies. Installation is straightforward for many doors, but a few reviewers ran into finicky alignment or setup steps.
Pros
-
If you are replacing another Kwikset deadbolt, the footprint and standard door prep can make swaps easier, with minimal changes to the door.
-
Across reviews, the lock generally operated consistently without jamming, and the auto-relock feature performed reliably when enabled.
-
SecureScreen (decoy/random digits) helps prevent fingerprint-based code guessing, and Z-Wave versions mention encryption; the keywayless design also removes common key-based attack vectors like bump keys.
-
Auto-relock/auto-lock features are commonly praised for convenience and worked consistently in testing, but toggling settings may require opening the interior panel and using small switches.
-
Keywayless entry reduces the risk of traditional picking and bump-key attacks; reviews do not provide an explicit drill-resistance rating.
-
The illuminated touchscreen keypad is central to the design and is generally responsive and easy to use, though a few reviewers note it can take multiple touches to wake.
-
The glossy, minimalist touch surface looks premium on modern doors but can smudge; SecureScreen and anti-fingerprint coatings help reduce obvious fingerprint trails.
-
Access history is available in some setups (and was highlighted in early coverage), but in practice it can depend on the hub and platform, and not every controller app exposes detailed logs.
-
Removing the keyway reduces exposure to key-based attacks, but otherwise Obsidian is a standard deadbolt without advanced intrusion sensing or active defense features.
-
Unlocking is generally quick once the keypad wakes, but some reviewers reported slower wake behavior and slightly slower operation in hot, sunny conditions.
-
The exterior build is described as sturdy and the mechanism proved reliable in use, but at least one reviewer reported sloppy bolt machining that made installation harder.
-
Z-Wave Plus versions cite over-the-air firmware update capability, but overall functionality remains intentionally minimalist and still depends on the hub ecosystem.
-
Many reviewers found setup straightforward with good hardware options, but others ran into alignment issues, confusing instructions, or a tricky handing/calibration step that required rework.
Cons
-
Obsidian stores up to 16 codes on the standalone model and up to 30 codes on connected versions, with 4 to 8 digits per code; code limits and scheduling features vary by model and ecosystem.
-
Integration centers on Z-Wave hubs (such as SmartThings, Wink, and Control4) with Alexa/Google voice control typically routed through that hub; multiple reviews call out missing native HomeKit support.
-
The lock provides audio/LED indicators (including low-battery alerts) and hub apps can show lock state, but native, lock-specific push notifications are limited and platform-dependent.
-
Voice control generally works for locking and status checks through Alexa/Google when paired with a hub, but unlocking by voice is often restricted for security.
-
Powered by four AA batteries with low-battery warnings and external 9V jump terminals for emergencies; battery life reports vary (some cite roughly 5 to 6 months), and battery access can require partial disassembly.
-
Pricing is mid-to-premium for a touchscreen deadbolt; value is better if you already own a Z-Wave hub, but paying extra for a hub and living with limited code controls can reduce perceived value.
-
When paired to a Z-Wave hub, reviewers were able to lock/unlock and check status remotely, but code management and other functions can be restricted by the chosen platform.
-
You can add/remove PINs and use an optional master code, but advanced guest access controls (expiring or scheduled codes) are limited or unavailable on some models and hubs.
-
Motor noise is noticeable to some reviewers, who describe the mechanism as loud during operation.
-
App support is inconsistent: some versions rely on a smart-home hub app rather than a dedicated Kwikset app, which can limit advanced controls like remote code creation on certain platforms.
-
The black exterior can absorb heat in direct sun; at least one reviewer noted it can get hot to the touch and may slow slightly under high heat.
-
Reviews note no full door-open/closed alerting, but some describe auto-lock behavior that only triggers when the door is closed and may beep when it is not fully shut.
-
Most smart features require a compatible Z-Wave hub; without it, Obsidian behaves like a standalone keypad deadbolt.
-
There is no built-in Wi-Fi; remote access typically depends on Z-Wave plus a hub rather than direct Wi-Fi connectivity.
-
Obsidian is keywayless, so there is no physical key override if electronics fail; the emergency fallback is the external 9V jump terminals plus your PIN.
-
Multiple reviews explicitly note there is no Bluetooth, so there is no phone-proximity unlock or key fob option.
-
Reviews note no built-in alarm/siren, so there is no siren loudness benefit to rely on.
FAQ
Does the Kwikset Obsidian have a physical key backup?
No. Obsidian is keywayless, so entry is by PIN (or through a connected hub setup). If the batteries die, you can use the external 9V terminals to power it long enough to enter a code.
Do I need a hub for smart features?
For remote control, voice assistants, and most smart-home routines, yes: the connected model relies on Z-Wave and typically needs a compatible hub. The keypad works without a hub.
How many user codes can it store?
Depending on the model, Obsidian supports up to 16 codes (standalone) or up to 30 codes (connected), with 4 to 8 digits per code and an optional master code.
Will it work with HomeKit or Google Home?
Reviews note no native HomeKit support, and voice control usually depends on pairing the lock to a Z-Wave hub and then using Alexa or Google Assistant through that platform.
How often will I change batteries?
It uses four AA batteries and gives low-battery warnings, plus has 9V jump terminals for emergencies. Reported life varies, with some users citing around 5 to 6 months depending on usage and conditions.
