The Xiaomi Smart Door Lock G100 is Xiaomi’s latest addition to its growing smart home ecosystem. Designed to combine advanced security with everyday convenience, this smart lock brings AI-powered fingerprint recognition, multiple unlocking options, and deep smart home integration into a compact and modern design.

With features like a financial-grade security chip and nine unlocking methods, the G100 is built for users who want both peace of mind and seamless access control.

Xiaomi Smart Door Lock G100 Features

C-Grade Lock Cylinder for Enhanced Security

At its core, the G100 uses a direct-insert C-grade lock cylinder with a clutch mechanism. This provides strong resistance against forced entry attempts and improves overall durability compared to traditional locks.

AI Fingerprint Recognition with High Accuracy

The lock features AI-powered fingerprint recognition with a fast 0.5-second unlock speed and 99.29% accuracy. Over time, the system learns and adapts, improving recognition speed and reliability with continued use.

Nine Unlocking Methods for Maximum Flexibility

Xiaomi offers a wide range of unlocking options, including:

  • AI fingerprint recognition
  • Bluetooth unlocking
  • NFC access
  • Emergency key

  • Virtual password input

This flexibility ensures that users can always access their home, even if one method is unavailable.

Advanced Security with Financial-Grade Chip

The G100 includes a financial-grade security chip that ensures encrypted communication and secure local data storage. It also protects against electronic interference and malicious attacks, which is crucial for a connected device like a smart lock.

Anti-Tamper and Safety Alerts

Security is further enhanced with anti-pry and anti-tamper protections. Additionally, the lock can detect if the door is left open and send alerts, helping prevent accidental security risks.

Coercion Fingerprint for Emergency Situations

Remote access requires a Bluetooth Mesh gateway, which enables full smart home functionality.

Long Battery Life with Emergency Power Option

Powered by four AA batteries, the lock can last up to 12 months on a single set. For emergencies, a USB-C port is available to provide temporary power, ensuring you’re never locked out.
