The TCL K1 smart door knob is now official, marking the company’s first entry into smart door hardware. Built from aerospace-grade aluminum with a brushed nickel finish, it combines durability with rapid biometric access and app-based controls.
TCL K1 smart door knob offers fast biometric security
At the core is a fingerprint scanner that unlocks the door in just 0.3 seconds. TCL allows storage for up to 100 fingerprints, making it practical for family, guests, or office use. If you’d rather not rely on fingerprints, the K1 provides alternatives:
- Mechanical key
- Numeric passcode
- App-based unlocking
- One-time passcodes via TCL Smart Life (Tuya) app
These extra methods ensure flexibility across different scenarios, from Airbnb rentals to service staff access.
Huawei Watch D2 Blue Edition launches early in Europe and the UK with discounts that make it cheaper than last year’s models.
Modes built for convenience and control
The K1 comes with two distinct locking modes. Passage mode keeps the door unlocked during high-traffic times, while private mode restricts entry to administrators only. Automatic locking is supported as well, adding another layer of convenience.
Battery life, dimensions, and pricing
The smart door knob runs on four AAA batteries, with TCL claiming up to 12 months of use before replacements are needed. It’s compact at 7.5 x 21 x 8 inches and weighs around 1.2 kg. With IP53 dust and splash resistance, it’s built to handle everyday conditions, though it skips voice assistant integration.
Priced at $79.99, the TCL K1 smart door knob is available now through TCL’s official store and Amazon in a silver finish. For buyers seeking a reliable and affordable entry-level smart lock, TCL’s first attempt comes loaded with the essentials.
