TCL D2 Pro Palm Vein Smart Lock

The TCL D2 Pro is a smart deadbolt built around touchless palm vein recognition, identifying the unique vein pattern beneath the skin to unlock in about 0.3 seconds. Biometric data is stored locally, keeping palm information on the device rather than relying on cloud storage.

With Matter support and built-in Wi-Fi, the lock works with Apple Home, Alexa, and Google Home while enabling remote control, access monitoring, notifications, and temporary guest access. Six unlocking options—palm vein, keypad, key fob, physical key, app, and voice—provide alternatives for different household members and situations.

A 10,000mAh rechargeable battery provides extended operation between charges. The aluminum-alloy exterior is designed for outdoor use, with IP55 protection and an operating range of -13°F to 158°F. Auto-lock adds another layer of everyday security by locking the door automatically after entry or exit.
