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.
Access logs are repeatedly described as detailed, showing who locked/unlocked and which method was used, supporting accountability and household tracking.
Reviews note no built-in alarm/siren, so there is no siren loudness benefit to rely on.
An alarm is mentioned for failed attempts and jam events, and some demos show volume controls, but loudness itself is not rigorously evaluated in the reviews.
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 app is described as feature-rich for access sharing, logs, and automations, but one hands-on review notes clunky device selection and occasional onboarding or calibration retries.
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.
Auto-lock is described as configurable with delays and schedules, but practical intelligence may be limited because at least one hands-on review says there is no door-ajar sensor. Auto-unlock is presented primarily via arrive-home automations (location-based routines), which depend on phone location permissions and user setup rather than a dedicated proximity sensor.
Backset compatibility appears solid: multiple install demos note the latch can be adjusted to fit common door prep measurements.
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.
Battery life is commonly described around eight months using eight AA batteries; USB-C emergency power and a physical key are emphasized as backup access paths, while at least one reviewer dislikes the non-rechargeable approach.
Multiple reviews explicitly note there is no Bluetooth, so there is no phone-proximity unlock or key fob option.
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.
Build quality is described as improved versus the older version, with tempered glass, gaskets, and a lower-profile design helping it feel more premium than its price suggests.
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.
Evidence is mixed: one hands-on review explicitly says there is no integrated door-ajar sensor, while other writeups imply door-detected behavior; overall, door-sense is not consistently validated.
If you are replacing another Kwikset deadbolt, the footprint and standard door prep can make swaps easier, with minimal changes to the door.
Reviews and demos suggest standard deadbolt installation with typical door prep, including the ability to reuse common existing door hardware components like strike plates.
Z-Wave Plus versions cite over-the-air firmware update capability, but overall functionality remains intentionally minimalist and still depends on the hub ecosystem.
Fingerprint access is commonly described as very fast and improving over time, though at least one hands-on review notes occasional missed scans rather than perfection.
Finish durability is positioned around tempered glass with anti-glare and smudge or scratch resistance, with multiple sources framing the new exterior as more resilient and modern-looking.
Geofencing-style automations are highlighted in app demos, including routines that lock when leaving and unlock when arriving, positioned as a standout convenience feature.
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.
Guest access is a strong point: reviews cite up to 50 codes, plus one-time and scheduled codes that can expire automatically for visitors and contractors.
Most smart features require a compatible Z-Wave hub; without it, Obsidian behaves like a standalone keypad deadbolt.
Multiple reviews explicitly emphasize no hub is required for Wi-Fi remote control, improving simplicity and total cost.
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.
Installation is generally portrayed as quick DIY with included hardware, though one review notes minor tool-fit friction and occasional setup retries during onboarding or calibration.
Jam-related protection is mentioned via jam alarms or warnings, and calibration behavior is described as retracting and extending to avoid binding during normal use.
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.
The addition of a mechanical key is repeatedly framed as an important reliability upgrade for emergencies and battery-related scenarios.
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 keypad is described as illuminated and responsive, with anti-peep entry supported so users can add extra digits before or after the real PIN.
Unlocking is generally quick once the keypad wakes, but some reviewers reported slower wake behavior and slightly slower operation in hot, sunny conditions.
Lock and unlock speed is consistently described as quick across fingerprint, keypad, and app control, including claims of roughly half-second fingerprint entry.
Motor noise is noticeable to some reviewers, who describe the mechanism as loud during operation.
The locking motor is generally described as quiet, and operation sounds or chimes are referenced as adjustable in app settings.
Across reviews, the lock generally operated consistently without jamming, and the auto-relock feature performed reliably when enabled.
Locking reliability is broadly positive in hands-on use, with users describing consistent locking and unlocking via multiple methods.
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.
Reviews mention activity and security notifications, including alerts tied to failed attempts or tamper events, with no consistent complaints about delivery.
Removing the keyway reduces exposure to key-based attacks, but otherwise Obsidian is a standard deadbolt without advanced intrusion sensing or active defense features.
Physical security is generally positioned as solid for typical homes, with BHMA or ANSI Grade 2 level claims cited in multiple sources, but not presented as top-tier Grade 1 hardware.
Keywayless entry reduces the risk of traditional picking and bump-key attacks; reviews do not provide an explicit drill-resistance rating.
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.
Remote access is consistently described as responsive for locking/unlocking and checking status from anywhere through the Wyze app.
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.
Security posture is framed around local biometric storage and standard app-based control; reviews emphasize fingerprints staying on-device rather than in the cloud, but do not deeply audit encryption specifics.
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.
Smart-home integration is largely limited to Alexa and Google (including routines), with multiple sources explicitly noting no HomeKit or Matter support at launch.
Tamper and failed-attempt alerts are referenced, including alarm triggers and app notifications, though sensitivity tuning and real-world false positives are not deeply tested.
The glossy, minimalist touch surface looks premium on modern doors but can smudge; SecureScreen and anti-fingerprint coatings help reduce obvious fingerprint trails.
The tempered-glass touch surface is framed as a meaningful design upgrade, improving visibility and modernizing the exterior compared with the earlier version.
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.
User management is generally described as straightforward, with options for permanent, recurring, temporary, and limited-access roles.
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.
Across reviews, the standout theme is value: a sub-$100 price for Wi-Fi remote control, keypad, and fingerprint access is repeatedly framed as best-in-class for budget buyers.
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.
Voice control is described in the context of Alexa and Google routines for locking, while unlocking by voice is typically restricted for security.
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.
IP53 weather resistance is frequently mentioned as adequate for typical residential use, though one review calls it less impressive than some competitors.
There is no built-in Wi-Fi; remote access typically depends on Z-Wave plus a hub rather than direct Wi-Fi connectivity.
Built-in Wi-Fi (commonly described as 2.4GHz) is praised as the biggest upgrade, enabling true remote monitoring and control without helper devices.
