TCL Unveils D2 Pro Palm Vein Smart Lock with 0.3-Second Unlocking--Open 'Like Iron Man' to Redefine Home Security

Three-model D2 Series Debuts with AI-powered Local Storage and Versatile Smart Features

NEW YORK, July 3, 2025 /PRNewswire/ -- Global smart-home leader TCL today launches its all-new D2 Series Smart Locks, headlined by the flagship TCL D2?Pro Palm Vein Smart Lock. Building on the remarkable success of the first-generation D1?Pro in 2025--garnering multiple Best of CES honors and rave reviews from leading media outlets, and securing the #1 sales rank on Amazon for smart locks priced above $150--the D2?Pro raises the bar with industry-leading AI-driven palm vein recognition and 100% on-device data storage. Complemented by the D2?Plus and D2 models, the series addresses a wide range of budgets and use cases, bringing next-generation access control to households worldwide.

Key Features

AI-Driven Palm Vein Recognition
99.9999% accuracy (tested under controlled laboratory conditions), unaffected by moisture, dirt, or age, surpassing fingerprint and face-recognition solutions.
0.3-second unlock for instantaneous access, reliable in all lighting and weather conditions. Open like Iron Man with a simple wave.

100% Local Data Storage
Biometric templates and access logs reside solely on the device--no cloud transmission or remote dependency, eliminating hacker-targeted data leaks.
Flexible guest management with temporary PINs and shareable QR codes, plus tiered permission levels for family, friends, or service providers.

Long-Lasting Power & Emergency Backup
Built-in 10,000?mAh battery provides up to 240 days of continuous operation on a single charge.
Low-battery alerts via on-device LED and app notifications, plus a USB-C emergency power port for on-the-spot charging.
