What matters in practice

The differences that matter

The wrong door cannot be fixed in the app

Start with the lock opening before comparing smart features.

How we reached this conclusion

U300 operates a lever latch. U100 operates a deadbolt. Their different mechanical jobs remain different even though both offer Home Key and fingerprint entry.

Two locks may solve two different doors

A home can reasonably use U100 at the front and U300 at an interior office.

How we reached this conclusion

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.

A shared Apple feature can have different setup costs

Budget the required Apple Thread hub when choosing U300.

How we reached this conclusion

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.

What you give up

Every choice has a cost

  • Home Key needs a compatible Thread-enabled Apple home hub.

If you choose Aqara Smart Lock U100

  • Remote Aqara and Matter features use an Aqara hub.

Recommendation switch

The decision flips if...

The door inspection finds a lever-only opening

Choose Aqara Smart Lock with Handle U300. U300 matches that mechanical job.

The component being replaced is a separate deadbolt

Choose Aqara Smart Lock U100. U100 matches the deadbolt job.

Your landlord requires the exterior hardware unchanged

Choose neither. Choose a compatible interior retrofit with permission instead.

What matters in practice

How to make the call

01

Look at the door first

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.

02

Map the network hardware

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.

03

Office traffic and exterior exposure

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.

Check these before buying

  • Identify whether the target opening is for a lever latch or a separate deadbolt.
  • Confirm the required Apple home hub for U300 Home Key, or the correct Aqara hub for U100 remote features.

What this comparison cannot tell you

  • Door fit also depends on bore, backset, trim clearance and local installation requirements. No security-grade winner is inferred from lock shape.
