Building on the first-generation D1 Pro’s incredible success in 2025, which saw it win multiple Best of CES awards, receive overwhelmingly positive reviews from major media outlets, and rank #1 on Amazon for smart locks costing more than $150, the D2 Pro sets the standard with industry-leading AI-driven palm vein recognition and 100% on-device data storage. The D2+ and D2 models round out the series, which covers a broad variety of budgets and use cases and gives houses all around the world next-generation access control.
