Main trade-off
Aqara Smart Lock U50
No fingerprint entry.
Head-to-head
Aqara Smart Lock U50 vs Aqara Smart Lock U100: U100 adds fingerprints, it does not remove bridged Matter’s hub requirement
The short answer
Choose U50 when phone taps and keypad codes cover your household and its offer costs less. Choose U100 when fingerprint entry matters or you want its published IP65 outer-panel rating. Both use Zigbee and Bluetooth, so moving to U100 does not eliminate the hub needed for their bridged Matter setup.
Before you choose
The reasoning and the trade-offs
Home key alone does not require the upgrade
A household that already prefers tapping an iPhone or Apple Watch can use either model. The U100 premium buys a different entry option, rather than unlocking Apple home key for the first time.
What this is based on
Both official product pages document Apple home key. U100 separately lists fingerprint recognition, which is absent from U50's documented entry methods.
Main trade-off
Aqara Smart Lock U100
The same door-thickness limits and Zigbee bridge requirements remain.

- Choose it for
- Use Apple home key and codes without paying for an unused fingerprint reader
- Keep the same Zigbee hub plan when the U50 offer is lower

- Let household members unlock with a fingerprint
- Choose the documented IP65 outer panel instead of U50's IPX5 rating

What matters in practice
The differences that matter
Home key alone does not require the upgrade
A household that already prefers tapping an iPhone or Apple Watch can use either model. The U100 premium buys a different entry option, rather than unlocking Apple home key for the first time.
How we reached this conclusion
Both official product pages document Apple home key. U100 separately lists fingerprint recognition, which is absent from U50's documented entry methods.
Do not replace a hub budget with a model upgrade
Choosing U100 instead of U50 leaves the same broad networking task. For a Matter installation, include a compatible Aqara bridge and the requirements of your chosen platform.
How we reached this conclusion
Both specification tables list Zigbee and Bluetooth. Aqara documents Matter through a supported Aqara hub for these Zigbee locks.
The battery headline is one-third longer, with limits
Eight months is about 33% above six months on paper. It is useful as a maintenance estimate, not a promise that U100 will last one-third longer under your radio signal and entry habits.
How we reached this conclusion
(8 - 6) / 6 × 100 = 33.3%. Aqara states up to 6 months for U50 and up to 8 months for U100, with usage assumptions.

Meaningful differences
What changes the fit
| What changes | Aqara Smart Lock U50 | Aqara Smart Lock U100 | Why it matters |
|---|---|---|---|
| Fingerprint entry | No fingerprint reader | Fingerprint reader | U100 adds a phone-free entry method that U50's keypad cannot provide. |
| Outer-panel rating | IPX5 | IP65 | Both publish water protection. Only U100's stated rating includes dust protection. |
| Manufacturer battery estimate | Up to 6 months | Up to 8 months | These are manufacturer estimates, not a measured two-month advantage in your home. |
| Wireless architecture | Bluetooth and Zigbee | Bluetooth and Zigbee | Neither is a native Matter-over-Thread lock. Their Matter route uses a compatible Aqara hub. |
| Door thickness | 35 to 55 mm | 35 to 55 mm | The more expensive lock does not extend the stated door-thickness range. |
What you give up
Every choice has a cost
If you choose Aqara Smart Lock U50
- The stated outer-panel rating is IPX5, without a dust-protection digit.
If you choose Aqara Smart Lock U100
- The longer battery estimate is not a measured runtime guarantee.
Recommendation switch
The decision flips if...
Fingerprint entry is a daily requirement
Choose Aqara Smart Lock U100. U100 adds the fingerprint reader.
Phone taps and codes are enough and U50 costs less
Choose Aqara Smart Lock U50. Its documented entry methods cover that plan without the fingerprint upgrade.
Native Matter over Thread is mandatory
Choose neither. Both use Zigbee and require a bridge for their Matter route.
What matters in practice
How to make the call
Choose the entry method people will actually use
Walk through how each person enters the house. U50 already covers a phone or watch tap, codes and a physical backup key. U100 is easier to justify if someone regularly leaves their phone behind and prefers a fingerprint to remembering a code. That is a concrete daily difference.
Keep the network architecture straight
The Amazon listing subtitles should not decide your hub purchase. Aqara's own specifications identify these as Zigbee and Bluetooth devices. Basic local operation and the different smart-home integrations have different requirements. Plan the Aqara hub and Apple-home setup for the features you want before comparing the lock-only offers.
Weather and batteries need modest expectations
U100's IP65 rating adds a documented dust-protection classification beyond U50's IPX5 rating. Neither rating makes installation quality irrelevant. Battery-life figures also come from manufacturer assumptions. Keep replacement AAs and a backup entry method available, then treat actual low-battery notifications as the maintenance trigger.
What this comparison cannot tell you
- We have not tested fingerprint recognition, weather resistance, lock security or battery life. Manufacturer estimates and IP classifications are not field measurements.
