Bottom Line
Choose Aqara U100 for Apple Home Key plus a fast fingerprint reader at a fair price; Skip it if you need built-in Wi-Fi or you do not want to rely on hubs for the best remote control and integrations.
Best for
Apple-first homes that want Home Key plus a consistently fast fingerprint unlock, and also want flexible guest access, logs, and automations without paying top-tier Home Key lock prices.
Not for
Anyone who demands built-in Wi-Fi and zero hub dependence, or who needs to re-key the cylinder to match existing house keys. Also not ideal if you refuse to keep a physical backup method for rare connectivity or auto-lock edge cases.
Verdict
Aqara's U100 is one of the strongest Apple-first smart locks because Home Key is seamless, the fingerprint reader is consistently quick, and you still get keypad, NFC, app control, and a hidden key for backup. The Aqara app offers richer logs, user management, one-time and timed codes, and plenty of alert and automation knobs, while HomeKit covers the basics well. The tradeoff is connectivity: there is no built-in Wi-Fi, so remote control and Matter/Alexa/Google features depend on hubs. Reliability is generally solid, but a few long-term reports mention occasional offline or auto-lock calibration hiccups, so keep a physical backup method handy.
Pros
-
The motor is often described as powerful with high torque and fast actuation, helping the deadbolt throw confidently. Proper alignment is still important to avoid binding on the strike.
-
Failed-attempt lockout is widely described as effective: after multiple incorrect entries, the lock disables certain methods for up to about 30 minutes. This helps deter brute-force attempts and is often configurable.
-
The exterior portion is IP65-rated and reviewers report it tolerates heat, cold, and rain well. The interior unit is not weather-rated but is protected indoors.
-
Supports common backset sizing (2-3/8 and 2-3/4) and is generally compatible with typical North American deadbolt spacing when installed to spec.
-
A hidden physical keyway plus included keys provide a dependable backup, and multiple reviewers recommend carrying a key in case of connectivity or power issues. Manual operation from inside remains simple via the thumbturn.
-
Fingerprint unlocking is consistently a standout: fast (often cited under 0.5s) and accurate, with storage kept on-device. Wet fingers or cuts can cause retries, but overall performance is excellent.
-
Security is reinforced with AES-128 style encryption claims and on-device fingerprint storage, which reviewers view positively for privacy. The feature set focuses on secure access methods and auditability rather than ultra-high-security cylinders.
-
The exterior housing is frequently described as heavy, sturdy, and premium-feeling (zinc-alloy/metal), while the interior side is more plastic. Overall durability impressions are strong, with some long-term cosmetic wear noted.
-
Lock and unlock actions are generally quick, especially via fingerprint and Home Key, with responsive bolt movement. App and auto-lock actions can show small delays depending on connectivity and settings.
-
Most reviewers found installation straightforward for standard deadbolts, with clear in-app tutorials and a required calibration step. Older doors sometimes need drilling or chiseling for a smooth bolt throw.
-
Day-to-day locking is usually reliable, but a minority of long-term reports mention occasional offline freezes or auto-lock calibration mishaps. Firmware updates and a reset often improve stability, and a physical backup is advised.
-
Integration is a major strength: Apple Home/Home Key and Siri work well, and with an Aqara hub the lock can expand to Matter, Alexa, Google Home, and IFTTT. A few ecosystem-specific quirks and hub dependencies are the main downsides.
-
Activity logs are a strong feature, showing who unlocked the door and by which method in many cases. One limitation noted is that HomeKit-related unlocks can appear as a generic HomeKit event rather than the exact method used.
-
The touchscreen keypad is widely praised for being backlit, responsive, and easy to use for 6-10 digit codes. Minor nitpicks include needing to wake it first and, in some workflows, pressing a confirm/lock button.
-
Value is frequently rated high, especially when discounted and compared with other Home Key locks. The main price caveat is that adding hubs can push the total closer to premium competitors.
-
The touch interface is generally sensitive and satisfying, with a matte finish that helps readability and reduces fingerprint marks. Night visibility is typically strong thanks to the backlight.
-
The lock provides audible chirps/voice prompts and a door-not-locked alarm, with adjustable volume levels and do-not-disturb options. Loudness is generally adequate for awareness rather than a full security siren.
-
Voice control is strong via Siri/HomeKit, while Alexa and Google typically require an Aqara hub and may need extra setup steps. Voice unlocking commonly uses a PIN or platform security gating.
-
Brute-force mitigation is solid, with alarms, visual warnings, and a lockout after repeated failed attempts that disables keypad/fingerprint temporarily. Sensitivity and lockout timing are typically adjustable.
-
Geofencing and location-based automation options are available primarily through app automations and platform routines. They can be powerful but may be labeled beta and require always-on location permissions.
-
Auto-unlock behaviors are mainly achieved through automations (for example, location-based routines or ecosystem rules) rather than a pure hands-free proximity unlock. These can work well but may depend on hubs and platform security prompts.
-
Guest access is flexible with one-time and temporary codes and shareable passes, and HomeKit can also generate guest codes. A recurring day-of-week/time window schedule is a noted limitation in several reviews.
-
Battery life is often rated around 8 months on four AA cells and many users report strong endurance, while a few long-term accounts cite faster drain. USB-C emergency power and a physical key mitigate low-battery scenarios.
-
Remote access is achievable through a HomeKit hub and/or an Aqara hub, enabling remote lock control, status checks, and code management. Without a hub, control is typically limited to Bluetooth range.
-
The Aqara app provides deeper control than HomeKit (logs, codes, users, alerts, automations), and the UI is generally considered capable. Some reviewers dislike the firmware update flow, Bluetooth connection wait time, or needing to be near the lock for certain settings.
-
Auto-lock is feature-rich (door-close sensing, timers, schedules, passage mode), and many find it convenient. However, some reviews label it beta and report occasional misfires or latch problems if calibration or door alignment is off.
-
User management supports multiple users, fingerprints, passcodes, and (Aqara) NFC credentials with per-user limits. Apple Home's access management is simpler and may not expose the same scheduling and log detail.
-
Door-sense relies on a gyroscope/accelerometer to infer open/closed/ajar status and trigger alerts or auto-lock. Accuracy is generally good after calibration, but a few reviewers report occasional false readings or less-than-perfect precision.
-
Bluetooth is the default direct connection and usually works reliably within range, though initial connections can take a few seconds. Binding to an Aqara hub can shift more traffic to Zigbee and feel snappier for remote tasks.
-
Notifications cover unlock events, door-not-locked warnings, and various alerts, with do-not-disturb controls available. Some long-term feedback mentions missed alerts or occasional incorrect status reporting in the app, often improving after updates.
-
Fits many standard single-cylinder deadbolt doors, but door prep matters: small misalignment can cause friction or latch issues. Measure carefully and expect occasional hole/strike adjustments on older hardware.
-
Firmware updates can add features and improve stability over time, and several reviewers cite meaningful improvements after updates. The update process can be more manual than expected (download to phone, transfer over Bluetooth).
-
Some reviews cite BHMA/ANSI compliance and sturdy construction for basic physical resilience, but it is not positioned as the highest-grade security hardware. The practical security story is the combination of durability, alerts, and logs.
-
Some owners report the finish can scratch or show wear over months, especially on darker colors, even though it does not affect operation. The keypad coating is often praised for resisting smudges.
-
Pick/drill resistance is not emphasized with a top-tier rating in these reviews, and several discussions imply it is similar to typical consumer smart lock cylinders. If high-security cylinder performance is a priority, this may not be the best match.
Cons
-
Hubs are optional for basic local use but commonly required for the best experience: Apple Home remote access needs a Home hub, and Matter/Alexa/Google/IFTTT and many remote features need an Aqara hub. This adds cost and setup complexity.
-
Re-keying is a common pain point: several reviewers say the cylinder and pins are nonstandard or hard to swap, making matching existing house keys difficult without a locksmith-level workaround.
-
There is no built-in Wi-Fi radio, so the lock itself cannot connect directly to a router. Remote control and broader integrations rely on an Apple Home hub and/or an Aqara Zigbee hub acting as the bridge.
FAQ
Do I need a hub for remote access?
For remote control in Apple Home, you need an Apple Home hub like a HomePod or Apple TV. For remote features in the Aqara app and for Matter/Alexa/Google/IFTTT integrations, you typically need an Aqara Zigbee hub.
Does the U100 have built-in Wi-Fi?
No. The lock itself uses Bluetooth (and Zigbee when bound to an Aqara hub). A hub provides the bridge to Wi-Fi for remote access and broader platform support.
How well does the fingerprint reader work?
Reviews consistently describe it as very fast and accurate, with fingerprints stored on the device. Wet fingers or cuts can cause occasional retries, but overall performance is a highlight.
Can I create guest or temporary access codes?
Yes. You can create one-time and time-bounded codes and manage users in the Aqara app, and Apple Home can also manage access codes for Home users and guests. Several reviews note limitations for recurring day-of-week and time-of-day schedules.
What happens if the batteries die?
You can unlock with the physical key, or temporarily power the exterior unit via the USB-C port to regain access. Battery life is often reported as strong, but experiences vary, so low-battery planning is still smart.
Can I re-key it to match my existing keys?
Many reviewers report re-keying is difficult because the cylinder/pins can be nonstandard or hard to swap. Plan to use the included keys or consult a locksmith if matching existing keys is a must.
