Xiaomi has introduced the Smart Door Lock 5C, a new piece of smart home hardware currently on pre-sale in China for 659 yuan (roughly $98). It is a standard smart lock that focuses on physical security hardware and multiple entry methods, including integration with Xiaomi’s existing device ecosystem.
Xiaomi Smart Door Lock 5C Specifications
The lock is built around a C-class straight-in lock cylinder. To prevent tampering, Xiaomi placed the clutch mechanism entirely inside the main lock body. This means that if the exterior panel is broken off or the outside handle is forced down, the internal mechanism keeps the door secured. On the inside, there is a physical deadlock knob. The door automatically locks when closed, and lifting the handle engages an additional locking mechanism.
For entry, the lock relies primarily on a semiconductor fingerprint scanner located on the handle. According to Xiaomi, the scanner reads prints in half a second and updates fingerprint data over time to maintain accuracy. It also includes a duress fingerprint setting. You can register a specific finger that will unlock the door while silently sending an alert to an emergency contact.
If you prefer not to use biometrics, the lock supports standard PIN codes, temporary passwords, and virtual passwords that allow you to type random numbers around your actual PIN to hide it from anyone watching. It can also be unlocked using a traditional mechanical key, Bluetooth, or NFC via compatible Xiaomi phones, smart watches, and fitness bands.
The device connects to the Mi Home app and supports Xiaomi HyperOS Connect. When paired with a Bluetooth Mesh gateway, the lock can trigger smart home routines, such as turning off the air conditioning when you leave the house. Internal sensors monitor the hardware and send remote alerts to your phone if the door is left open, if an incorrect PIN is entered multiple times, or if someone attempts to remove the front panel.
The lock runs on four standard AA alkaline batteries, which are rated for up to 12 months of use. If the batteries run low, an emergency button allows for a few final unlocks. If the batteries die completely, you can plug a standard power bank into a USB-C port on the exterior to temporarily power the lock and get inside. The lock comes in a sandblasted Starry Black finish and is rated to operate in temperatures from -25°C to 70°C.
In related news, Xiaomi has recently launched the Mijia Pressurized Steam Iron with 500kPa pressure and 135°C steam, along with a new 600L refrigerator featuring an automatic ice maker and dual cooling system.
