Xiaomi has introduced the Xiaomi Smart Door Lock 5, a new smart home security product designed to make everyday access more convenient while adding practical emergency unlocking features. Officially announced on November 4, 2026, the smart lock is now available for pre-order through Xiaomi’s official sales channels in China, with an introductory price of 999 yuan.
One of the biggest upgrades is Xiaomi’s newly developed automatic noise-reduction lock mechanism. The device also features fingerprint recognition, multiple unlocking options, remote monitoring, and an emergency power solution designed to help users avoid getting locked out when the battery runs low.
Quieter Automatic Locking Mechanism and C-Class Lock Cylinder
The Xiaomi Smart Door Lock 5 features Xiaomi’s latest self-developed fully automatic noise-reduction lock body. It automatically locks the door when it closes, reducing the need to manually secure the entrance.
For additional mechanical protection, Xiaomi has equipped the device with a direct-insertion C-class lock cylinder. This design combines automatic locking convenience with a higher-security mechanical locking structure.
The quieter locking mechanism is particularly useful for households that prefer less noise when entering or leaving the home, especially during nighttime hours.
Fast Fingerprint Recognition and Multiple Unlocking Methods
Fingerprint recognition is one of the main access methods on the Xiaomi Smart Door Lock 5. According to Xiaomi’s specifications, fingerprint identification takes no more than 0.7 seconds, with a stated recognition accuracy of at least 99.53%.
Beyond fingerprint access, the smart lock supports several alternative unlocking methods:
-
Fixed passwords
-
Virtual passwords for added privacy
-
Temporary one-time passwords
-
NFC access cards
-
Bluetooth unlocking
-
Traditional mechanical keys
These options provide greater flexibility for different household members and visitors, allowing users to choose an appropriate access method for different situations.
New Emergency Start Button Helps Prevent Lockouts
A notable addition to the Xiaomi Smart Door Lock 5 is its new emergency start button, which provides an extra unlocking option when the battery level becomes critically low.
Even if the smart lock automatically shuts down because of insufficient power, users can press the emergency start button and continue unlocking the door with a fingerprint or password.
If the batteries are completely depleted, the lock also provides a USB-C port at the bottom of its exterior panel. Users can connect a power bank or another compatible external power source to temporarily supply electricity and restore access.
This emergency power design offers a practical solution for situations where users forget to replace the batteries in time.
Up to 12 Months of Battery Life
The Xiaomi Smart Door Lock 5 uses eight AA batteries as its primary power source. Xiaomi claims that the battery life can reach approximately 12 months under normal usage conditions.
Actual battery life may vary depending on unlocking frequency, network connectivity, and daily usage habits.
Combined with its emergency start button and USB-C backup power option, the lock is designed to provide more reliable operation and reduce concerns about unexpected battery depletion.
Real-Time Security Monitoring and Intelligent Alerts
Security monitoring is another important part of the Xiaomi Smart Door Lock 5. The device can monitor the locking mechanism in real time and notify users when unusual activity is detected.
Supported security alerts include:
-
Door not fully closed: Sends an alert if the door is left slightly open.
-
Tampering detection: Notifies users if someone attempts to pry open the exterior panel.
-
Repeated failed verification: Detects multiple unsuccessful unlocking attempts.
-
Duress fingerprint detection: Triggers an alert when a designated duress fingerprint is used.
These monitoring features help homeowners stay informed about their door’s status and identify potentially suspicious activity.
Wi-Fi, Bluetooth 5.3, and Mi Home App Connectivity
For smart home integration, the Xiaomi Smart Door Lock 5 supports both Wi-Fi and Bluetooth 5.3 connectivity.
Through the Mi Home app, users can remotely check the lock’s status and receive relevant security notifications. This makes it easier to monitor the entrance even when they are away from home.
The smart lock also supports temporary access sharing through a WeChat mini program. Users can generate temporary digital keys for visitors, providing a convenient way to grant short-term access without handing over a physical key.
