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.
Reviews highlight detailed event history in the app, with lock/unlock entries tied to user and method; one reviewer notes being able to review long windows of history for shared spaces.
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 Lockly app is generally described as clean and responsive for basic lock/unlock, logs, and settings, but some reviewers found PIN and guest workflows overly complicated compared with rivals.
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-locking is widely praised and configurable (often cited in the 5–300 second range), helping the door re-secure itself without relying on habits.
A lockout style safeguard is described that disables keypad input after too many failed attempts, reducing brute-force code guessing.
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 described as strong on four AA cells, and the external 9V jump option reduces the risk of lockouts when batteries die.
Multiple reviews explicitly note there is no Bluetooth, so there is no phone-proximity unlock or key fob option.
Bluetooth performance is usually fast and stable for in-range control, though at least one review reports occasional trouble discovering the lock on some phones during setup.
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.
Multiple reviews describe the hardware as sturdy and premium, but also noticeably large and heavy compared with sleeker competitors.
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.
A door sensor is mentioned as an optional add-on to report open/closed state, but it is not consistently tested across reviews.
Most reviewers report compatibility with standard doors, but at least one install required extra door prep (strike/side bracket work) and the weight can make alignment more sensitive.
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.
The 3D fingerprint reader is repeatedly called fast and accurate; enrollment takes multiple scans but day-to-day unlocking is a standout convenience.
One review cites strong finish coverage, including a lifetime warranty on exterior finishes, supporting long-term cosmetic durability expectations.
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.
Access sharing is a strength: reviews mention temporary, scheduled, one-time, offline codes, and app-based sharing options; however, some find the onboarding and messaging flow confusing for casual guests.
Most smart features require a compatible Z-Wave hub; without it, Obsidian behaves like a standalone keypad deadbolt.
Out of the box the lock is Bluetooth-first, and multiple reviews note that a separate Wi-Fi hub is needed for remote control and voice assistants.
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 experiences vary from quick (around 15 minutes) to frustrating; the app guidance helps, but the heavy hardware and documentation can make assembly and alignment harder than average.
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.
Backup entry options are well covered, with a traditional key cylinder and an exterior 9V jump-power method noted for dead batteries.
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 PIN Genie keypad that shuffles digit positions is consistently praised for improving code privacy, though a reviewer notes it can feel disorienting for people who remember codes by shape.
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 actions are commonly described as quick, including near-instant app commands within Bluetooth range and a few-second mechanical cycle.
Motor noise is noticeable to some reviewers, who describe the mechanism as loud during operation.
Motor operation is described as relatively quiet compared with typical smart deadbolts.
Across reviews, the lock generally operated consistently without jamming, and the auto-relock feature performed reliably when enabled.
Most reviews describe solid day-to-day operation, but one outlet reports calibration/status mismatches that made locked vs unlocked reporting unreliable in their testing.
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.
Push notifications are specifically called out as missing versus competing smart locks.
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 locking/unlocking is not available without the optional Wi-Fi hub; with the hub, reviews describe convenient anywhere access through the 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 is a core theme: reviewers cite AES256/BLE security claims, the PIN-shuffling keypad, biometric anti-spoofing, lockout behavior, and privacy mode style controls.
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 without accessories; Alexa and Google support is tied to the Wi-Fi hub, while HomeKit, Matter, Thread, and IFTTT-style automation are repeatedly noted as absent or limited.
The glossy, minimalist touch surface looks premium on modern doors but can smudge; SecureScreen and anti-fingerprint coatings help reduce obvious fingerprint trails.
The touchscreen is generally responsive and easy to read, but its glossy surface can show fingerprints; its main value is supporting the dynamic PIN layout.
At least one review describes multi-step account or device activation verification (codes via SMS and email), indicating stronger account protection than many simple Bluetooth locks.
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 and guest management is feature-rich, offering multiple access types and schedules, but the depth can feel like overkill and harder to administer for short-term visitors.
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 the most common knock: reviewers call it expensive for a Bluetooth-first lock, especially once the Wi-Fi hub accessory is added.
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 not native; Alexa and Google voice commands are described as available only when paired with the Wi-Fi hub.
Warranty coverage is described as strong (including finish and electronics coverage), but reviewers also flag usability and setup complexity as an area needing improvement.
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.
One review explicitly praises weather toughness across extreme temperatures, suggesting good outdoor suitability when installed correctly.
There is no built-in Wi-Fi; remote access typically depends on Z-Wave plus a hub rather than direct Wi-Fi connectivity.
There is no built-in Wi-Fi in the base lock; Wi-Fi connectivity is achieved through an add-on hub or bundled variant, which affects total cost and complexity.
