TCL has launched its first smart door knob, the K1, as part of its expanding smart home product lineup. The K1 supports multiple access methods and features a fast fingerprint sensor powered by AI. It is priced at $79 in the United States.
TCL K1 Smart Lock Specifications
The TCL K1 smart lock unlocks in just 0.3 seconds using a built-in AI-enhanced fingerprint sensor. The system learns and adapts over time, improving recognition accuracy with repeated use. In addition to fingerprint access, users can unlock the door using a password, the TCL smart app, or a physical key.
TCL has equipped the K1 smart door knob with several privacy-focused features designed to give users full control over access and data security. All data is stored locally on the device, with no reliance on cloud syncing or third-party servers, ensuring sensitive information stays private.
Using the companion app, users can generate temporary passcodes, set access schedules, and monitor real-time entry logs. The app enables flexible access management, making it easy to customize who can enter and when.
The K1 supports smart modes, including Privacy Mode, which locks the door from the inside for admin-only access; Passage Mode, which keeps it unlocked during high-traffic periods; and Auto-Lock, which automatically secures the door after closing.
The device runs on four AAA batteries and promises up to 12 months of operation. It supports an operating temperature range of -25°C to 70°C. The build uses aerospace-grade aluminum alloy and has a brushed metal finish. The door knob weighs approximately 1.2kg and measures 17.5cm x 21cm x 8cm.
TCL has rated the K1 with IP53 ingress protection, making it resistant to dust and light splashes. It is designed for use in homes, offices, and garages.
