The catch
Aqara Smart Lock U50
Lacks fingerprint entry.
Side by side
U50 is the pick when phone taps and keypad codes cover your household and its offer costs less. U100 is the pick when fingerprint entry matters or you want its published IP65 outer-panel rating. Because both use Zigbee and Bluetooth, moving to U100 does not remove the hub that their bridged Matter setup needs.
Before you buy
Either model works for a household that already prefers tapping an iPhone or Apple Watch. The U100 premium buys a different entry option. Apple home key is already on both.
Where this comes from
Apple home key is documented on both official product pages. U100 also lists fingerprint recognition separately, and U50’s documented entry methods don’t include it.
The catch
Lacks fingerprint entry.
The catch
Door-thickness limits and Zigbee bridge requirements stay the same.

Before replacing a US deadbolt, see how Aqara U50 and U100 differ on fingerprint entry, Apple home key, outdoor exposure and hub requirements.
U50 is the pick when phone taps and keypad codes cover your household and its offer costs less. U100 is the pick when fingerprint entry matters or you want its published IP65 outer-panel rating. Because both use Zigbee and Bluetooth, moving to U100 does not remove the hub that their bridged Matter setup needs.
Which one fits
Apple home key works on both, using compatible Apple devices.
The fingerprint reader comes only with U100.
Each is a Zigbee/Bluetooth lock. The bridged Matter route they use isn’t the same as native Thread.
The thickness limits listed for both are identical. Check all other installation dimensions too.
In practice
Either model works for a household that already prefers tapping an iPhone or Apple Watch. The U100 premium buys a different entry option. Apple home key is already on both.
Apple home key is documented on both official product pages. U100 also lists fingerprint recognition separately, and U50’s documented entry methods don’t include it.
Picking U100 over U50 leaves the broad networking task as it was. For a Matter installation, plan for a compatible Aqara bridge and the requirements of the platform you choose.
Zigbee and Bluetooth appear in both specification tables. For these Zigbee locks, Aqara documents Matter through a supported Aqara hub.
On paper, eight months is about 33% above six months. Treat it as a maintenance estimate. It is not a promise that U100 will last one-third longer given your radio signal and entry habits.
(8 - 6) / 6 × 100 = 33.3%. Aqara gives up to 6 months for U50 and up to 8 months for U100, based on usage assumptions.

Aqara, DL-D05D
This keypad deadbolt supports Apple Home Key and comes with physical backup keys. Adding a Zigbee hub extends it to remote access and smart-home routines.

Aqara, DL-D01D
Entry options listed are fingerprint, home-key, keypad and phone, and the documented door range is 1.375 to 2.17 inches thick.
Spec by spec
| Spec | Aqara Smart Lock U50 | Aqara Smart Lock U100 | In practice |
|---|---|---|---|
| Fingerprint entry | No fingerprint reader | Fingerprint reader | U100 brings an entry method that needs no phone, which U50’s keypad can’t offer. |
| Outer-panel rating | IPX5 | IP65 | Water protection is published for both. Dust protection appears only in U100’s stated rating. |
| Manufacturer battery estimate | Up to 6 months | Up to 8 months | They are manufacturer estimates and not a two-month advantage measured in your home. |
| Wireless architecture | Bluetooth and Zigbee | Bluetooth and Zigbee | Neither lock is native Matter-over-Thread. A compatible Aqara hub carries their Matter route. |
| Door thickness | 35 to 55 mm | 35 to 55 mm | The stated door-thickness range isn’t extended by the more expensive lock. |
Trade-offs
Change of plan
Go with Aqara Smart Lock U100. The fingerprint reader is what U100 adds.
Go with Aqara Smart Lock U50. Its documented entry methods handle that plan and skip the fingerprint upgrade.
Neither model fits. Zigbee is used by both, and each needs a bridge for its Matter route.
Decision guide
U50 fits when phone taps and keypad codes cover your household and its offer costs less. U100 fits when fingerprint entry matters or you want its published IP65 outer-panel rating. Both use Zigbee and Bluetooth, which means stepping up to U100 does not remove the hub their bridged Matter setup needs.
Think through how each person gets into the house. A phone or watch tap, codes and a physical backup key are already covered by U50. If someone regularly leaves their phone behind and would rather use a fingerprint than remember a code, U100 is easier to justify. That is a concrete daily difference.
Do not let the Amazon listing subtitles decide your hub purchase. Aqara's own specifications describe these as Zigbee and Bluetooth devices. Basic local operation and the various smart-home integrations each have their own requirements. Before comparing lock-only offers, plan the Aqara hub and Apple-home setup around the features you want.
Compared with the IPX5 rating of U50, the IP65 rating of U100 adds a documented dust-protection classification. Installation quality still matters with either rating. Battery-life figures rest on manufacturer assumptions too. Keep replacement AAs and a backup entry method on hand, and let actual low-battery notifications tell you when to do maintenance.
