Main trade-off
Aqara Smart Lock with Handle U300
Cannot replace a deadbolt.
Head-to-head
Choose U300 for a compatible lever-latch door. Choose U100 for a separate deadbolt. Their shared fingerprint and Home Key features do not make their hardware interchangeable.
Before you choose
Start with the lock opening before comparing smart features.
What this is based on
U300 operates a lever latch. U100 operates a deadbolt. Their different mechanical jobs remain different even though both offer Home Key and fingerprint entry.
Main trade-off
Cannot replace a deadbolt.
Main trade-off
Cannot replace a lever latch.


Compare Aqara U300 and U100 by the door hardware they replace, their Matter connection, Home Key requirements and exterior weather ratings.
Choose U300 for a compatible lever-latch door. Choose U100 for a separate deadbolt. Their shared fingerprint and Home Key features do not make their hardware interchangeable.
Winner by situation
U300 is a lever latch, not a deadbolt replacement.
U100 needs a compatible deadbolt opening.
Both include a fingerprint reader, subject to correct hardware fit.
Both replace exterior hardware. An interior retrofit is a different product type.
What matters in practice
Start with the lock opening before comparing smart features.
U300 operates a lever latch. U100 operates a deadbolt. Their different mechanical jobs remain different even though both offer Home Key and fingerprint entry.
A home can reasonably use U100 at the front and U300 at an interior office.
A front entrance may have a separate deadbolt while an office has a lever latch. Matching each product to its hardware is more useful than naming one household-wide winner.
Budget the required Apple Thread hub when choosing U300.
U300's Home Key route requires the compatible Apple Thread home hub. U100's local Home Key route does not require an Aqara hub, while its remote Aqara features do.

Meaningful differences
| What changes | Aqara Smart Lock with Handle U300 | Aqara Smart Lock U100 | Why it matters |
|---|---|---|---|
| Door hardware | Lever handle and latch replacement | Deadbolt replacement | The door preparation decides which product can physically serve the job. |
| Matter connection | Native Matter over Thread | Matter through compatible Aqara hub | The existing smart-home hardware can favor one installation route. |
| Home Key setup | Compatible Thread-enabled Apple home hub required | Home Key supported without an Aqara hub for local tapping | A U300 purchase can add an Apple hub requirement even when both locks advertise Home Key. |
| Exterior rating | IPX4 | IP65 | U100 specifies dust protection and a different water-test level. |
| Passage routine | Lever passage mode keeps the latch accessible | Deadbolt can be left unlocked | A passage lever suits frequent movement through an office or side door. |
What you give up
Recommendation switch
Choose Aqara Smart Lock with Handle U300. U300 matches that mechanical job.
Choose Aqara Smart Lock U100. U100 matches the deadbolt job.
Choose neither. Choose a compatible interior retrofit with permission instead.
What matters in practice
A lever below a deadbolt is not evidence that either product will fit the same opening. Identify which component you want to automate, then measure its bore, backset and thickness.
U300 fits a Thread-based Matter installation. U100 is a Zigbee device that uses an Aqara hub for its fuller connected feature set. Avoid ordering a hub solely because it has the same brand name.
The U300 passage feature can suit a door used repeatedly during the day. For an exposed entrance, respect the exact installation and weather guidance rather than treating any IP rating as permission for all conditions.
