The catch
Aqara Smart Lock B50
Lacks fingerprint and Home Key.
Side by side
Code-based entry and optional Aqara Matter bridging suit B50, while C220 adds fingerprint access. Direct Wi-Fi remote control comes on both, so for that basic use a separate hub does not decide anything.
Before you buy
Avoiding a hub for basic remote control alone doesn’t justify paying for C220.
Where this comes from
Built-in Wi-Fi comes with both locks. B50 needs an Aqara hub just for the specified Matter bridge route and not for its ordinary remote Aqara app connection.
The catch
Lacks fingerprint and Home Key.
The catch
Has no Home Key and no documented Matter integration.

Keypad against fingerprint entry, direct Wi-Fi access, battery changes and Aqara Matter bridging requirements are where B50 and C220 are compared.
Code-based entry and optional Aqara Matter bridging suit B50, while C220 adds fingerprint access. Direct Wi-Fi remote control comes on both, so for that basic use a separate hub does not decide anything.
Which one fits
No fingerprint reader comes with B50.
Direct Wi-Fi connectivity is on both.
Home Key is unsupported on both.
The compatible Aqara bridge is needed for B50. C220 has no such path documented.
In practice
Avoiding a hub for basic remote control alone doesn’t justify paying for C220.
Built-in Wi-Fi comes with both locks. B50 needs an Aqara hub just for the specified Matter bridge route and not for its ordinary remote Aqara app connection.
Eight AA cells are needed for a full change, up from four.
8 divided by 4 is 2. Because runtime conditions differ, this can’t be carried straight over to twice the annual battery cost.
Pick whichever missing capability your home will really use.
B50 offers an optional Matter route through a bridge but no fingerprint reader. C220 has fingerprints, though no Matter route is documented for it.

Aqara, DL-D12E
Remote app control works without an extra hub on this Wi-Fi keypad deadbolt, which also has physical backup keys and optional Aqara Matter bridging.

eufy Security, T8506
You can enter by fingerprint, keypad or phone, and the documented door range is 1.375 to 2.17 inches thick.
Spec by spec
| Spec | Aqara Smart Lock B50 | eufy Security Smart Lock C220 | In practice |
|---|---|---|---|
| Fingerprint reader | Not included | Included | C220 gives an entry method with no phone or code. |
| Battery count | Four AA cells | Eight AA cells | A full change on C220 takes twice as many cells. |
| Exterior rating | IPX3 | IP53 | Dust protection is part of C220’s published rating. Both have 3 as the water numeral. |
| Matter connection | Through a compatible Aqara bridge | No documented Matter path | Setting up Matter on B50 means hardware on top of its built-in Wi-Fi. |
| Remote Wi-Fi | Built-in 2.4 GHz Wi-Fi 6 | Built-in Wi-Fi | Basic remote app use works on both without a separate bridge. |
Trade-offs
Change of plan
Go with eufy Security Smart Lock C220. The reader you need is on C220.
Go with Aqara Smart Lock B50. That optional integration is documented for B50.
Neither model fits. Go with a model that has Home Key instead.
Decision guide
B50 is the fit for code-based entry with optional Aqara Matter bridging. C220 adds fingerprint access. Because both give direct Wi-Fi remote control, a separate hub is not what decides that basic use.
If visitors get a code, B50 is sufficient. Fingerprints on the C220 are most useful for recurring users who can be enrolled in advance. They do little for one-time guests.
Each lock connects to Wi-Fi for its own app control. Check the network signal at the closed door. Matter is a question of ecosystem integration beyond that shared ability.
Keep the right number of batteries on hand and follow each installation guide. C220's dust rating is a documented difference, but the water-test level is the same in IPX3 and IP53.
By the numbers
What we found across the smart locks we compare, plus the checked facts behind each finding.
None of the 25 models checked meets all of “Hand a code to family and guests”, “Use a fingerprint to unlock”, “Run it remotely without needing a hub”, and “Base the setup on Matter”, so the pick goes to the closest practical compromise.
0 models fit, out of 25 checkedHow we countedThe count uses each product's current fit ratings for “Hand a code to family and guests”, “Use a fingerprint to unlock”, “Run it remotely without needing a hub”, and “Base the setup on Matter”. A need with no documented match is not counted.
