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.
