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.
Event/activity logs are repeatedly mentioned, with reviewers noting access to doorbell and lock/unlock histories and the ability to review event records inside the app.
Reviews note no built-in alarm/siren, so there is no siren loudness benefit to rely on.
Audio/alarm volume is adjustable in the app and reviewers note it can be loud by default during setup; the ability to tune or mute sounds is a plus, but audio quality for doorbell recordings was criticized by at least one reviewer.
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 Lockin app is widely described as feature-packed and customizable (modes, power management, access controls, event viewing), but multiple reviewers also flagged rough edges such as hidden controls, missing/immature video history features at launch, slow clip loading, and occasional troubleshooting or resets.
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 widely praised and highly configurable (immediate to timed delays). The built-in door-closed sensing helps prevent locking before the door is shut, improving real-world reliability.
Wrong-try protection and lockout behavior are described as available and configurable, adding a practical layer of protection against repeated code attempts.
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 framed as roughly three months for the Pro, with USB-C charging and emergency power options. Several reviews highlight an optional solar panel that can meaningfully top up the battery, although placement and looks are a frequent complaint.
Multiple reviews explicitly note there is no Bluetooth, so there is no phone-proximity unlock or key fob option.
Bluetooth is used in setup/bridging to Wi-Fi in several reviews and is generally portrayed as convenient during onboarding.
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 impressions are mostly positive: reviewers call the lock hefty, solid, and less plastic-heavy, though the exterior assembly is bulky and at least one reviewer criticized hardware tolerances (bolts/threads) as a quality-control pain point.
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.
The integrated door-open/closed sensing via the strike plate and smart deadbolt is repeatedly called out as a smart, cleaner alternative to external sensors and is tied to better auto-lock behavior and door-status awareness.
One review provides specific door thickness and bore-fit guidance and generally treats the lock as compatible with standard deadbolt installs; the main fit concern raised is bulk rather than incompatibility.
If you are replacing another Kwikset deadbolt, the footprint and standard door prep can make swaps easier, with minimal changes to the door.
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 usually described as quick and usable, but experiences vary: some found it reliable, others needed multiple tries or noted setup is slower than palm enrollment and can be harder for some users (including kids).
Geofencing is mentioned as present in some materials and apps, but reviewers say it is limited, often used for changing modes/settings rather than true automatic lock/unlock behavior.
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 features are a highlight: reviewers cite one-time, temporary, and scheduled PIN codes and easy sharing, though some note restrictions (temporary access may be PIN-only, and permission tiers/time restrictions for full users can be limited).
Most smart features require a compatible Z-Wave hub; without it, Obsidian behaves like a standalone keypad deadbolt.
For ecosystem control, reviewers note you may need a Matter controller hub (or similar hub) to add the lock to platforms like Apple Home, Google Home, Alexa, or SmartThings; hub use often comes with reduced feature depth versus the Lockin app.
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 often reported as a straightforward 10–15 minute swap for a standard deadbolt, with guided in-app setup, but one critical review cited poorly machined/jamming long bolts and lots of cable routing that can make assembly more frustrating than typical.
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.
A physical key is included and used as a backup method; no review reported key override failures, and several call out the presence of emergency power as an additional fallback.
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 seen as useful for kids/guests and as a backup method, but at least one reviewer criticized poor outside usability (a non-illuminated lock button and unclear manual locking cues).
The keyway is typically hidden behind the doorbell button and presented as a practical backup; reviewers do not report pick/drill testing, but also do not flag obvious keyway quality problems in normal use.
Unlocking is generally quick once the keypad wakes, but some reviewers reported slower wake behavior and slightly slower operation in hot, sunny conditions.
Lock/unlock responsiveness is frequently described as very fast (both biometrics and app control), though overall perceived speed can be undercut when video clips or app functions lag.
Motor noise is noticeable to some reviewers, who describe the mechanism as loud during operation.
Across reviews, the lock generally operated consistently without jamming, and the auto-relock feature performed reliably when enabled.
Locking reliability is rated highly in several hands-on tests, but one critical review characterized the product as still beta-like, requiring reboots/force-quits and not yet fully trustworthy without more firmware refinement.
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 often described as fast and informative (motion/doorbell/lock events), but at least one reviewer reported major notification failures that required support and factory resets, and another noted limited per-alert toggles in the app.
Removing the keyway reduces exposure to key-based attacks, but otherwise Obsidian is a standard deadbolt without advanced intrusion sensing or active defense features.
At least two reviews cite BHMA/ANSI Grade 2 level certification for the lock, suggesting solid baseline physical security for residential use, though most testing focused on convenience and software rather than attack trials.
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 control via the Lockin app is positioned as a core strength (live view, lock/unlock, codes, alerts), though performance varies by reviewer, with some praising responsiveness and others reporting lag or slow video clip loading.
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.
Some reviewers highlight on-device processing, local storage, and direct device-to-phone style connections (often described as more private), but concrete third-party verification details are limited; advanced security claims should be weighed against real-world software stability.
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 compatibility is frequently advertised as broad (Matter/Thread plus major platforms), and pairing generally works, but reviewers repeatedly note that third-party apps expose only basic lock functions and omit many advanced features (especially doorbell/camera and granular access controls).
Anti-tamper and unusual-activity detection are referenced (including tamper events surfaced in some ecosystem apps), but few reviewers deeply tested sensitivity or false-alarm behavior.
The glossy, minimalist touch surface looks premium on modern doors but can smudge; SecureScreen and anti-fingerprint coatings help reduce obvious fingerprint trails.
The touch interface is often described as responsive and modern, with some praise for smudge resistance; however, visibility/UX issues (fish-eye video framing noted elsewhere, and unlit button behavior) can reduce ease of use at night.
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 organized (multiple palms/fingerprints/PINs per user), but at least one reviewer criticized limited permission granularity, with full users effectively receiving always-on access.
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 depends heavily on price: reviewers see the all-in-one concept and no-subscription local storage as compelling, but MSRP is considered expensive, and early-bird pricing is viewed as much more competitive given software maturity concerns.
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 via assistants (Siri/Alexa/Google) is described as working for basic lock/unlock commands; richer smart-home routines are possible, but broader feature access still tends to live in the Lockin app.
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.
Multiple reviews cite IP65 weatherproofing and describe the lock holding up to rain/dust and outdoor conditions; long-term durability claims exist, but most evidence is short-to-medium term testing.
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 2.4GHz Wi-Fi is a recurring positive, enabling direct app control and remote features without a separate bridge for basic operation.
