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 consistently highlighted as useful and fairly detailed, showing who unlocked the door and by what method (PIN, fingerprint, app/remote, manual). A few experiences note the log view can be limited initially but loads more history as you scroll, making it practical for monitoring kids, guests, or service providers.
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 generally described as easy to set up and feature-rich (users, logs, settings, firmware), but polish varies. Several reviews mention occasional sluggishness or connection hiccups, and Wi-Fi setup can be frustrating on certain networks; standalone/manual programming is also reported as unreliable by at least one reviewer.
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 a major strength: it is configurable (seconds to minutes), and in Wi-Fi/door-sensor setups it can avoid locking when the door is open/ajar. A recurring minor complaint is that auto-lock being enabled by default can surprise new users, though it is easy to adjust or disable.
Backset compatibility is repeatedly described as standard (commonly 2-3/8 or 2-3/4). A couple of hands-on installs mention minor confusion/quirks during adjustment, but overall fit is framed as typical for U.S. doors.
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 varies by usage and connectivity: manufacturer claims range from months to longer, but reviewers report anything from about a month during heavy testing to multiple months in normal use. Strong low-battery warnings are commonly noted, and emergency USB power plus a hidden key reduce lockout risk.
Multiple reviews explicitly note there is no Bluetooth, so there is no phone-proximity unlock or key fob option.
Bluetooth pairing is generally described as straightforward and reliable for local control. Bridge-based setups rely on Bluetooth to link the lock to the bridge, and most reviewers report good day-to-day operation once paired.
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 frequently praised as solid, heavy, and secure-feeling. Several reviews reference commercial-grade claims (especially on the Wi-Fi model), while a few note the industrial look or plastic feel on some exterior elements; overall durability impressions skew strongly positive.
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 door sensor is widely viewed as a meaningful upgrade, enabling open/closed status, open-door alerts, and smarter auto-lock behavior that helps prevent locking when the door is ajar. Reviewers consistently frame it as useful for peace of mind and better automation.
Door compatibility is generally presented as standard deadbolt fit for typical U.S. doors, with common door thickness and bore/backset ranges. Most installs are described as straightforward when replacing an existing deadbolt, with extra work mainly if drilling new holes or correcting alignment.
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.
Firmware updates and software-driven features are commonly mentioned (adding or refining behaviors like Magic Shake, sensor-based auto-lock, and general stability). A caution appears in some user-feedback sections that updates or configuration changes can occasionally introduce issues, so keeping alignment and settings correct matters.
Fingerprint performance is a standout: most reviewers describe it as fast and accurate with quick setup. A few note that finger positioning/angle can matter and some users (especially older users in anecdotal feedback) may see inconsistent scans, but overall sentiment is strongly positive.
Geofencing behavior is mixed: some reviewers report a better experience than prior generations, while others call it unreliable or dependent on leaving a set radius before it will trigger properly. It can be helpful when tuned, but it is not the most universally dependable 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 repeatedly described as strong: temporary PINs, scheduled access windows, one-time codes, and shareable eKeys are highlighted as ideal for cleaners, dog walkers, and rentals. Logs tied to user identity improve accountability for shared access.
Most smart features require a compatible Z-Wave hub; without it, Obsidian behaves like a standalone keypad deadbolt.
Hub/bridge needs depend on the version: built-in Wi-Fi models remove the bridge requirement, while older bundles require a bridge placed close to the door (often described as within about 10 feet). Bridge requirement is a common source of complexity for voice assistants and remote features on non-Wi-Fi versions.
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 varies sharply by generation: Wi-Fi revisions are often described as much easier and faster than early versions, with some installs completing in under 10–30 minutes. Older versions are described as finicky, sometimes requiring tailpiece trimming and very careful screw tightness and alignment to avoid binding.
There is no clear mention of an automatic jam-detection feature, but jamming/binding scenarios come up: misalignment, overtightened screws, and door fit can cause resistance. Newer hardware revisions are described as reducing prior jamming issues, but proper alignment remains important.
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 hidden physical key is broadly viewed as a reliable backup, and emergency external power via a USB port adds another recovery option when batteries die. This layered fallback approach is frequently cited as a major practical advantage versus app-only smart locks.
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 earns praise for tactile buttons, backlighting, and the anti-peep feature that allows extra digits around the real code. A recurring usability nit is the circular layout, which some find slower than a traditional keypad, but most still consider it dependable and secure.
Keyway quality is not heavily evaluated, but one review explicitly notes a standard-style keyway (Schlage mentioned) and most emphasize that the keyhole is hidden behind a flip-down faceplate. As a backup entry method, it is generally framed as dependable and well-integrated.
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 speed is commonly described as quick, especially via fingerprint and keypad, with near-instant responses frequently noted in tests. Geofence-based behaviors can be slower or more conditional, but direct methods are consistently fast.
Motor noise is noticeable to some reviewers, who describe the mechanism as loud during operation.
The motor is often described as smooth and fast, but a couple of reviewers note it can be louder than some competing locks. Most still consider the sound level acceptable, and the faster action is often seen as a worthwhile tradeoff.
Across reviews, the lock generally operated consistently without jamming, and the auto-relock feature performed reliably when enabled.
Once installed correctly and aligned, locking reliability is usually described as excellent with consistent fingerprint/PIN/app operation. Reported reliability issues tend to cluster around connectivity (Wi-Fi pairing or app connection loss) and installation-related binding rather than everyday mechanical failures.
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 generally appreciated for remote awareness (lock/unlock events and battery alerts). Some app workflows are criticized for requiring per-user notification rules rather than a simple global option, but overall alerting is seen as helpful for security and household monitoring.
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 attack resistance is framed as strong on Wi-Fi/door-sensor variants that reference commercial-grade/Grade 1 claims, while at least one older evaluation notes the model was not officially certified and was described as closer to Grade 2 in spirit. Overall, reviewers still describe it as robust for typical residential use.
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 a key benefit when Wi-Fi is built in or when a bridge is used: reviewers frequently highlight being able to lock/unlock from anywhere and manage users remotely. Some note remote actions can be slower over Wi-Fi than Bluetooth and that Wi-Fi stability depends on signal quality and network constraints.
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 features commonly mentioned include dual-layer encryption claims, the anti-peep keypad, activity logs, and a lockout mode that disables electronic access. These are generally seen as meaningful safeguards, though account-level protections are not universally praised.
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 integrations are broad (Alexa, Google, IFTTT, and sometimes SmartThings), enabling routines and automations. The most consistent limitation is the lack of Apple HomeKit support; setup can also be a bit quirky depending on how platforms label the integration and which connectivity version you own.
The glossy, minimalist touch surface looks premium on modern doors but can smudge; SecureScreen and anti-fingerprint coatings help reduce obvious fingerprint trails.
At least one review explicitly criticizes the companion app for lacking two-factor authentication, even while other reviews mention phone-number verification during account creation. If account security is a top priority, this is a notable weakness compared with platforms that offer robust 2FA.
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 access management is repeatedly praised: multiple roles (admin/normal/temporary), schedules, usage limits, and support for many users with PINs and fingerprints. This flexibility is a primary reason reviewers recommend it for families, offices, and rental properties.
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 generally rated positively relative to competitors because it bundles many entry methods (fingerprint + keypad + app + key) and strong guest-management features. Some reviewers still call MSRP expensive, but discounts and the feature set often shift the judgment toward good value.
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 (Alexa/Google) is commonly supported, typically requiring a voice PIN for unlocking. Experience depends on version: Wi-Fi models simplify setup, while bridge-based versions add placement constraints but still work well once configured.
Warranty and support are not deeply reviewed across sources, but one review’s user-feedback roundup notes generally responsive customer support and replacement parts when needed. Most other coverage focuses more on features and setup than long-term service outcomes.
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 frequently cited through IP65 and wide operating temperature claims, with reviewers expecting it to hold up in typical outdoor conditions. Real-world endurance commentary is limited, but the overall framing is that it is designed for exterior exposure.
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 a major convenience upgrade on built-in models, enabling remote access without extra hardware, but 2.4GHz-only requirements are a recurring pain point—especially for certain mesh setups. Strong signal and correct band selection are repeatedly emphasized for stable operation.
