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/activity logging is a practical strength in real use: reviewers mention seeing who unlocked/locked and, in some cases, which fingerprint/user performed the action.
Reviews note no built-in alarm/siren, so there is no siren loudness benefit to rely on.
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 consistently described as clean and feature-rich, with detailed control over access, detection, notifications, and power modes. A recurring critique is that troubleshooting (especially calibration guidance) could be clearer, and some wanted phone-based tap/NFC unlock.
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 commonly praised for peace of mind and flexibility (including short delays and schedules). Some reviewers cautioned that auto-lock can be risky if your door isn’t reliably closed/aligned or if door state detection is imperfect.
Wrong-try protections are commonly described (lockdown/timeouts after multiple incorrect entries), helping reduce brute-force attempts and adding practical security beyond basic PIN entry.
Backset support is described as adjustable to common sizes (2 3/8 in and 2 3/4 in), which helps it fit typical deadbolt door prep.
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 a highlight: the 10,000mAh rechargeable pack is repeatedly described as lasting months, with long-term users charging only a few times per year when tuned (for example, human-only motion). Charging can take hours and you may need to supply your own USB-C power gear.
Multiple reviews explicitly note there is no Bluetooth, so there is no phone-proximity unlock or key fob option.
Bluetooth is commonly mentioned as part of the lock-to-bridge communication path. Reviewers generally describe it as functional, primarily as an invisible link in the overall system.
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 widely described as heavy-duty and mostly metal, but it is also frequently called large/bulky. One expert review wanted a bit more robustness to make it an easy, universal recommendation.
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.
Door state awareness appears mixed: at least one reviewer warned the lock may not reliably know whether the door is open or closed, which matters if you rely heavily on auto-lock behaviors.
Door fit is usually straightforward, but some doors may need extra attention: shallow strike-plate depth can trigger calibration failures, and tight tolerances mean misalignment can prevent reliable locking.
If you are replacing another Kwikset deadbolt, the footprint and standard door prep can make swaps easier, with minimal changes to the door.
At least one installation guide notes you may be able to reuse existing deadbolt hardware if it fits flush, reducing the need to replace every component.
Z-Wave Plus versions cite over-the-air firmware update capability, but overall functionality remains intentionally minimalist and still depends on the hub ecosystem.
At least one long-term reviewer highlighted meaningful feature additions via updates, such as unlocking directly from a live-view screen on supported cameras, improving day-to-day usability.
Fingerprint performance is polarizing: several owners describe it as among the fastest and most accurate they have used, while one expert reviewer struggled with repeated reads and wished for clearer activation feedback (lighting).
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 options are robust, including temporary or scheduled PIN codes and app-based access. Scramble passcode and other convenience/security options are frequently cited.
Most smart features require a compatible Z-Wave hub; without it, Obsidian behaves like a standalone keypad deadbolt.
The required plug-in chime/bridge is a core part of the experience: it enables remote connectivity and local storage, and many liked having a loud indoor chime. Downsides include extra setup steps and needing to provide your own microSD card.
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.
Most reviewers found installation similar to other full deadbolt replacements and generally manageable, but a few called out real-world friction: needing a second set of hands, long firmware updates, and careful mechanical alignment to avoid errors or motor strain.
Calibration and error states can present as jam-related warnings in the app for some installs, even when the deadbolt feels physically secure, creating nuisance alerts rather than true mechanical jams.
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 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 generally considered easy and reliable for daily use, with extra security options like scramble passcodes. One reviewer noted occasional wake-up/tap sensitivity issues before the keypad became responsive.
Unlocking is generally quick once the keypad wakes, but some reviewers reported slower wake behavior and slightly slower operation in hot, sunny conditions.
When the biometric reader works well, unlocks are described as extremely fast. However, experiences vary: some testers reported repeated attempts needed on the fingerprint sensor, while others called operation instant and consistent.
Motor noise is noticeable to some reviewers, who describe the mechanism as loud during operation.
The motor is sensitive to resistance: if the deadbolt/strike alignment is off, reviewers warned the motor may struggle or fail to complete a lock cycle. With good alignment, long-term users reported stable performance.
Across reviews, the lock generally operated consistently without jamming, and the auto-relock feature performed reliably when enabled.
Locking reliability is strong for many owners (including long-term use), but it is not universally flawless. Reported weak spots include finicky alignment/calibration states and occasional inconsistencies with certain external controls (like one-touch locking).
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.
Notifications are configurable and usually fast, but not perfect: a few reviewers saw delayed starts to recorded events, occasional missed motion/loitering triggers, or tradeoffs between faster alerts vs alerts that include thumbnails.
Removing the keyway reduces exposure to key-based attacks, but otherwise Obsidian is a standard deadbolt without advanced intrusion sensing or active defense features.
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 repeatedly described as convenient and reliable, including locking/unlocking from anywhere and checking lock status. Several reviewers highlighted using it for guests, contractors, or deliveries.
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 and privacy discussion centers on local storage and app behavior; one reviewer noted an on-screen encryption message before video streams to the bridge. Overall, the product is framed as privacy-leaning due to non-subscription local storage, with some mention of broader brand scrutiny.
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 limited compared to ecosystems that prioritize Apple: reviewers consistently note Alexa and Google support, but no Apple HomeKit, Matter, or IFTTT.
The glossy, minimalist touch surface looks premium on modern doors but can smudge; SecureScreen and anti-fingerprint coatings help reduce obvious fingerprint trails.
Touch controls are usually described as responsive and backlit, but at least one expert review reported needing multiple taps to wake the dark touchscreen at times.
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 broadly praised, including multiple users, fingerprints, and configurable access windows. Reviewers emphasized that it’s easy to add or adjust access in the app.
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.
Value is framed as strongest when the price is closer to the low-to-mid $300s, since it combines multiple devices and includes the chime/bridge. At full price near $400, reviewers still call it feature-rich, but expectations rise for perfect reliability and broad ecosystem support.
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 works through Alexa and Google Assistant in supported setups, including lock/unlock commands and, in at least one review, routines tied to doorbell events.
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.
Weather resistance is presented as strong on paper (including an IP65 rating in one review), and no reviewer reported weather-related failures in the provided transcripts.
There is no built-in Wi-Fi; remote access typically depends on Z-Wave plus a hub rather than direct Wi-Fi connectivity.
Wi-Fi is tied to the required bridge and is noted as 2.4GHz in at least one expert review. In general, connectivity is described as stable, with one review calling out distance guidance between lock, chime/bridge, and router.
