What matters in practice
The differences that matter
A lock-only price comparison misses the keypad
U200 includes the exterior credential hardware that August sells separately.
How we reached this conclusion
Compare U200 lock-plus-keypad contents with August lock, DoorSense and mounting parts. No keypad is included in the selected August package.
Both preserve the key, only one accepts Home Key
Mechanical-key retention and Apple tap entry are separate properties.
How we reached this conclusion
Both are interior retrofits that retain a compatible exterior key. U200 additionally lists Apple Home Key.
Remote access needs different existing equipment
Thread hardware can favor U200 while ordinary Wi-Fi can favor August.
How we reached this conclusion
U200 requires a compatible Matter controller and Thread border router for networked remote access. August has Wi-Fi built into the lock.

Meaningful differences
What changes the fit
| What changes | Aqara Smart Lock U200, Silver | August Wi-Fi Smart Lock, fourth generation | Why it matters |
|---|---|---|---|
| Included exterior input | Fingerprint and code keypad | No keypad in lock-only package | August keypad access costs an extra accessory. |
| Apple Home Key | Supported | Not supported | Apple Home integration on August is not the same as Home Key. |
| Remote network | Matter controller and Thread border router | Built-in Wi-Fi for August app | The existing home network can decide the easier setup. |
| Lock power | Rechargeable battery pack | Two CR123 batteries | Charging and replacement-cell routines differ. |
What you give up
Every choice has a cost
If you choose Aqara Smart Lock U200, Silver
- Fit depends on the existing cylinder or thumbturn geometry, so buyers should run Aqara's compatibility check before ordering.
If you choose August Wi-Fi Smart Lock, fourth generation
- CR123 cells are less common and Wi-Fi use can make replacement more frequent.
Recommendation switch
The decision flips if...
Replacing the full deadbolt is acceptable and you want fingerprints with direct Wi-Fi
Choose neither. C220 avoids the retrofit adapter and separate Thread hub path.
What matters in practice
How to make the call
For a rental with an unchanged exterior requirement
August lock-only hardware stays on the inside. U200 retains the mechanical exterior lock but adds a separate exterior keypad if you want its fingerprint and Home Key entry. Check permission for that keypad placement even when the original key still works.
For family members without the app
U200 includes code and fingerprint entry, making phone-free access part of the base package. August supports a separate keypad accessory, so compare the complete intended installation rather than the lock box alone. Neither retrofit bypasses the need for a smooth existing deadbolt.
For an established Apple home
A compatible Thread-capable home hub makes U200 easier to absorb into an existing setup. August offers direct app access over Wi-Fi but lacks Home Key. Decide whether tapping the watch is important before treating Apple Home compatibility as equivalent.
What this comparison cannot tell you
- Manufacturer feature documentation is used here. No burglary, battery-life or recognition-speed test was performed.
- Retrofit compatibility depends on the existing deadbolt and adapter. A matching door thickness alone does not establish fit.

Compared set
None of the 25 models checked covers every part of “Keep the lock outside unchanged”, “Make a reversible renter upgrade”, “Tap my phone or watch to enter”, and “Control it away from home without a hub”, so the recommendation favors the closest practical compromise.
