When the keyboard or lock battery level drops below 20%, the Smart Lock U300 will alert users in advance, and the lock will still work normally for about 2 weeks. In emergency situations, you can still unlock with a physical key or power the door lock through the USB-C interface.

Make sure your finger is dry and clean before trying to unlock. Since fingerprints may change over time, please re-register periodically. For children and the elderly, please update fingerprints regularly or register multiple fingers.

After 10 incorrect password entries, the lock will disable password input for 30 minutes. Use internal unlocking or Bluetooth unlocking to unlock. Additionally, you can adjust the lock duration in the Aqara Home App under "Settings" > "Failed Attempts Lockout".

Aqara Home users: Update firmware through the settings page. Keep your phone close to the device during the update process (15-20 minutes).

Aqara Home users: Bind the door lock to an Aqara M3, M100, or G5 Pro hub device to use remote features. Apple Home users: Need to connect to an Apple home hub (such as HomePod or Apple TV) and a Thread protocol gateway to achieve remote control.

The touch panel uses tempered glass material, with excellent transparency while being more durable and scratch-resistant. The outdoor panel uses a matte zinc alloy material for greater hardness. The indoor panel is made of plastic material with a metal coating on the surface, effectively preventing scratches and fingerprint residue.

There are no restrictions. The Aqara Smart Door Lock U300 supports all door opening directions, including left/right, inward/outward.

The external front panel (keyboard area) of the Aqara Smart Door Lock U300 has a waterproof rating of IPX4, which effectively protects against light daily water splashes, therefore it is not recommended for use in outdoor spaces.

Internal panel operating humidity: 0 ~ 93% RH

The U300 is powered by just 4 LR6 AA batteries. In emergency situations, you can use the USB-C charging port on the side of the external panel to power the device using an external power source.

The average battery life is 10 months, but this will vary depending on different working environments and conditions. Battery performance decreases in low-temperature environments. Battery life was determined by Aqara laboratories using LR6 AA batteries and simulating 10 wake-ups per day at 25℃.

1) If you are outside, you can power the lock through the emergency USB-C charging port at the external panel button. 2) If you are inside, simply replace the LR6 AA batteries.

If this lock is locked due to failed verification, you can still unlock normally through the application (Aqara Home/Apple Home) or mechanical key. After a few minutes, all verification functions will return to normal. You can also change the lock settings through the Aqara Home application.

The mechanical key is designed to provide normal unlocking in special emergency situations when users cannot use regular verification methods (fingerprint/password/mobile application/NFC/HomeKey). It is recommended to keep the key in your car or office, just in case.

The Aqara Smart Door Lock U300 supports up to 75 simultaneous passwords, including regular passwords and temporary periodic passwords. Additionally, up to 8 sets of one-time passwords can be generated per hour.

Supports 4 to 10-digit fixed numeric passwords. It also supports phantom passwords up to 20 digits (including 6-10 digit fixed passwords). A phantom password allows you to add any number before and after the fixed password to prevent intruders from peeking when you enter your password. The Aqara Home platform can set 6-10 digit fixed passwords, and if other Matter platforms can set 4-10 digit passwords, they are also compatible with the U300.

Yes. You can generate temporary one-time passwords through the Aqara Home application.

The Aqara Smart Lock U300 supports up to 25 fingerprints.

Install the Aqara Home App, add and connect the door lock, then set up fingerprints according to the App prompts. You can also press the settings button and follow voice prompts for local fingerprint setup.

If the Aqara Smart Door Lock U300 indicates fingerprint enrollment failure, make sure your finger is dry and that there is no obvious damage to the fingerprint. Complete fingerprint collection requires seven attempts. Press your finger completely on the recognition area and try changing the enrollment angle according to voice/Aqara Home App prompts (avoid repeatedly enrolling the same angle). For a better unlocking experience, we recommend enrolling the thumbprint of your dominant hand.

Make sure your finger is free from dirt or moisture, place your finger completely on the fingerprint recognition area, and try again. If multiple failures cause the fingerprint verification to be locked, use a password and delete the old fingerprint in the Aqara Home App, then set a new fingerprint. You can set multiple fingerprints to avoid verification failure due to issues with a single finger.

The fingerprint module unlocks after recognizing, comparing, and verifying the collected fingerprints. Elderly people with severely worn fingerprints and children with shallow or incomplete fingerprints may have reduced success rates with fingerprint unlocking. In such cases, it is recommended to use a password and NFC/HomeKey to unlock.

Compared to traditional electronic locks from other brands that relock the latch five to ten seconds after unlocking, during which time intruders can open the door by pressing the handle, creating a security risk. The Aqara Smart Door Lock U300 can automatically lock the door immediately, effectively preventing intruders from unlocking and tailgating.

Bluetooth 5.0 provides higher connection speed, stability, and power efficiency.

Since Bluetooth only supports 1-to-1 connections, the Aqara Smart Door Lock U300 can only connect to one phone at a time.

Install the Aqara Home App on your phone and add the door lock. Click the unlock icon on the App homepage, then press the handle to unlock. After adding the door lock to the Aqara Home App, you can also add it to HomeKit and unlock it via Bluetooth.

The initial administrator account is set up when the lock is first added to the Aqara Home App. An administrator account is required to enter local settings mode. The initial administrator account can add more administrator accounts on the Aqara Home App.

In the Aqara Home App, permissions are divided into three types: administrator, regular user, and temporary user. Administrator permissions support various credential unlocking methods, adding users, and lock function settings. Regular users can use password, fingerprint, NFC, and other unlocking functions. Temporary users only support periodic password unlocking.

The Aqara Smart Door Lock U300 supports up to 50 accounts: can be set as 50 administrator accounts or 49 regular accounts + 1 administrator account.
