Compare Aqara Smart Lock U100 vs Yale August Smart Lock

Activity logs were useful for seeing who used the lock, but HomeKit-sourced events were less detailed about the exact unlock method.

The activity log was useful in one review, but another reviewer reported a serious failure where an unlock event was not logged.

The built-in speaker/alarm was viewed as useful rather than extremely loud, with reviewers appreciating open-door and warning alerts.

The Aqara app offered deep control and setup help, but reviewers also criticized slow status updates, long-press controls, and a frustrating firmware process.

The app was widely praised as intuitive, responsive, and feature-rich, though one reviewer had severe app freezing during setup.

Auto-lock evidence was mixed, ranging from flawless or cool performance to beta-feature delays and at least one lockout caused by latch behavior.

Auto-lock was one of the strongest features, praised for flexibility and peace of mind, though one reviewer disabled it because it could lock them out.

Failed-attempt lockout was consistently viewed positively, with reviewers saying it worked as intended and helped deter brute-force attempts.

Battery impressions were mixed: some reported excellent life or no early drain, while others saw quick drain or disliked the lack of clear low-battery awareness.

Battery life was the most consistent weakness, with repeated concern about CR123 batteries, shorter lifespan, replacement cost, and one six-to-eight-week real-world result.

Bluetooth performance was acceptable to strong in short-range use, with minimal latency and stable connections reported despite general reservations about Bluetooth smart-home devices.

Bluetooth-range control was described as responsive in one review, with the lock reacting nearly immediately when pressed.

Reviewers consistently described the lock as solid, heavy, sturdy, or well-built, with only cosmetic design or material caveats in a few cases.

Build quality drew praise where discussed, with reviewers calling out high-quality materials and a solidly built feel.

Door-sense was useful and often praised, though one reviewer estimated it at about 80% accuracy and used an extra contact sensor for certainty.

DoorSense was praised when it worked and was considered worth installing, but one reviewer reported repeated calibration failures and incorrect open/closed status.

Fit was strongest on standard deadbolt doors; reviewers praised a perfect fit in one install but warned that other lock types or unusual deadbolts can complicate replacement.

Reviewers valued the retrofit deadbolt fit for renters and existing-door setups, though one installation was complicated by tight door trim.

One reviewer reused an existing strike plate successfully, suggesting some prior hardware can work when the bolt alignment is already right.

Keeping the outside hardware and existing deadbolt was repeatedly praised, especially for renters, maintenance access, and preserving exterior appearance.

Firmware updates were a tradeoff: one long-term reviewer said they improved performance, while another found the update process frustrating.

Fingerprint unlocking was the strongest area of agreement, with reviewers repeatedly calling it fast, accurate, reliable, and often their preferred method.

Fingerprint entry was treated as a missing keyless feature rather than a strength of this lock.

Finish impressions were mixed: some praised resistance to fingerprints and keypad marks, while a long-term reviewer said the dark finish scratched easily.

Geofencing was possible but evidence was cautious: one reviewer used it successfully, while another warned location automations were beta-like and risky.

Geofencing and auto-unlock were the most mixed smart feature: some reviewers found it handy or excellent, while others found it slow, inconsistent, or stopped working.

Guest access was useful for one-time, temporary, and shared passcodes, but several reviewers wanted more flexible schedules or noted user/password limits.

Guest access was easy and useful, with virtual keys, sharing by text, and scheduled codes highlighted positively.

Hub requirements were the biggest ecosystem tradeoff: some saw the bundled hub as a no-brainer, while others disliked needing extra hardware for remote and Matter features.

Reviewers liked that built-in Wi-Fi removes the need for an add-on bridge or Connect module.

Most reviewers found installation straightforward or easy, though one noted older or unusual deadbolt doors may require extra measuring or creative fitting.

Most reviewers found setup easy, quick, and well guided by the app, with one strong dissent reporting freezes, verification issues, and calibration trouble.

The physical key remained a useful backup, but reviewers framed it more as emergency insurance than a primary access method.

The retained physical key was useful as a fallback and for renters, but one long-term tester still ended up carrying keys because smart unlocking was not fast enough.

The keypad was generally well liked for responsiveness, readability, and satisfying operation, with minor complaints about extra confirmation steps or fingerprint wear concerns.

The optional keypad works and can be useful, but reviewers noted it is not included and may disappoint buyers who want a built-in keypad experience.

Keyway quality was the clearest mechanical weak spot because multiple reviewers found re-keying difficult or effectively not practical.

Locking and unlocking were repeatedly described as quick, especially through Siri, Home Key, and the fast motorized action.

App/manual locking was often described as instant, smooth, or quick, but one reviewer found physical keys faster than app, Siri, or watch workflows.

The motor was praised for quiet operation in PCMag testing.

Reliability was split: early testing was flawless for some reviewers, while longer-term users reported offline states, wrong status, and unresponsive behavior.

Locking reliability was excellent in most formal testing and one six-month review, but one reviewer reported serious state confusion and unreliable locking status.

Notifications and alerts were considered useful for knowing who unlocked the door, whether it was left open, or whether automations fired.

Notifications were a clear strength, with reviewers praising flexible smart alerts, quick push alerts, and better door-status awareness.

Physical attack evidence was limited, but one reviewer framed the lock’s lowest BHMA grade as still providing meaningful durability.

Physical security received strong praise from TechGearLab, which highlighted the ANSI Grade 1 strength rating and intruder resistance.

Pick-resistance evidence was limited and skeptical, with one reviewer assuming the U100 could still be defeated like many smart locks.

Remote access worked best with an Aqara hub or Apple home hub, but reviewers noted important limitations when controlling settings away from the lock.

Remote access was praised as convenient for controlling the lock from elsewhere in the house or anywhere with a phone connection.

Security features drew positive comments around AES encryption and local fingerprint storage.

Security software features were reassuring in the CNET review, especially authentication and encryption protections around the app and account.

Smart-home integration was a major strength, especially HomeKit/Home Key and Matter potential, but Alexa setup and Home Key lock limitations created caveats.

Smart-home integration was broad and often praised, but Alexa/Google setup hitches, HomeKit offline issues, and one severe HomeKit complaint made reliability mixed.

The touch surface was praised for feel, visibility, and brightness in both direct sunlight and hands-on use.

The lack of a built-in outside touchpad/touchscreen was a drawback for the reviewer who preferred that style of lock.

User access management was usually praised for clear controls, remote management, and multiple user types, despite app and code-management caveats.

User access management was praised for free virtual keys and scheduled access codes.

Value was broadly praised because the U100 packs Home Key, fingerprint, keypad, and smart integrations at a lower price than several named alternatives, though hub costs can raise the total.

Value was mixed: several reviewers called it pricey but worthwhile, while others weighed the high price against batteries, keypad add-ons, and reliability frustrations.

Voice control worked well in the cited tests, including Siri and Alexa examples, with voice access framed as one of several convenient unlock or lock methods.

Voice control worked quickly in one test and was supported broadly, but other reviewers reported password recognition issues or slow/failing Siri and Google Assistant use.

Support was viewed positively through a resolved battery-warning bug and confidence that August/Assa Abloy support would keep software maintained.

Weather resistance drew positive comments, including confidence in outdoor exposure and one reviewer reporting no issue during freezing conditions.

The lack of built-in Wi-Fi was a recurring limitation because remote control and long-distance features require a hub or router workaround.

Built-in Wi-Fi was praised for freshness, range, and eliminating a bridge, but reviewers tied it to battery drain and one reported mesh/Wi-Fi frustration.
