When we reviewed the first-generation TCL D2 Pro Palm Vein Smart Lock in September 2025, we praised its ease of installation and the speed with which it unlocked upon recognition of enrolled palms. TCL says this second-generation model is even faster, thanks to local AI learning that also improves the palm vein scanner’s accuracy.

Meanwhile, the new lock’s support for Matter-over-Thread should both increase its smart home ecosystem support and increase its battery life compared to the Wi-Fi radio in the original model. On that note, TCL says the D2 Pro will operate for up to 8 months on a single charge.

TCL didn’t publish ANSI or BHMA certifications for its earlier lock, but it says this new model is certified BHMA Grade 3. That actually means it’s rated ANSI Grade 3, and while that’s the lowest of the three ANSI grades, that standard is for commercial locks (BHMA certification is for residential locks). So, the new D2 Pro should prove to be very durable.

TCL says its biometric technology can recognize an authorized fingerprint in just 0.3 seconds. Matter-over-Thread support endows TCL’s new lever lock with even better battery life than its new smart deadbolt: up to 12 months on a charge.

The TCL D2L Fingerprint Lever Lock is likewise certified BHMA Grade 3, and it features Matter-over-Thread support for broad compatibility with smart home ecosystems, including Amazon Alexa, Apple Home, Google Home, and Samsung SmartThings.

TCL has not yet published prices for either the D2 Pro Palm Vein Smart Lock and D2L Fingerprint Lever Lock, but says both smart locks should be available for purchase in the second quarter of 2026.
