TCL Expands Smart Security Lineup with Matter-Enabled D2 Plus and D2L Lever Locks
0.3 seconds. That is the claimed fingerprint unlock latency on TCL's newly announced D2 Plus Matter and D2L Lever Smart Locks, per the company's release.

The figure sits at the top of the spec sheet for good reason: it is the single most marketable number on the page, and the rest of the announcement is engineered to support it.
The protocol layer
Both locks ship with Matter over Thread, not Wi-Fi-direct, as the primary interconnect. The choice matters. Thread is a low-power mesh radio that piggybacks on existing border-router-capable devices — HomePod mini, Apple TV 4K, Echo with Thread radio, or any Google Nest Hub — meaning the lock talks locally to the home's hub fabric rather than reaching out to TCL's servers for routine state changes. Pairing with Apple Home, Google Home, or Amazon Alexa is presented as a checkbox feature; in practice it depends entirely on which Thread border router the user already owns.
TCL also allows Wi-Fi to be disabled entirely, with the lock continuing to function over local Bluetooth or Thread. For users with concerns about telemetry egress, this is the most consequential detail in the release.
The biometric pipeline
Fingerprint templates are described as encrypted and stored locally on the device, with no cloud upload. TCL provides no documentation in the release on the specific algorithm, key length, or secure element architecture. The "AI-powered" and "self-learning" language is marketing scaffolding around what is, at minimum, an on-device template-matching routine. The 0.3-second figure likely reflects a controlled lab environment with pre-enrolled prints and a warm sensor; cold-finger, partial-print, or dirty-sensor performance is unverified.
The D2L integrates the sensor into the lever handle itself, allowing authentication during the natural grip-and-turn motion. On paper this reduces a two-stage interaction to one; in real-world deployment it introduces wear-pattern questions the release does not address.
Physical certification
Both models carry BHMA certification, covering rated resistance to impact, drilling, and forced-entry attempts. This is the standard baseline for residential deadbolts in North America and is a legitimate floor — not a ceiling. No smart-lock cybersecurity certification (e.g., ioXt, BSI) is cited.
Pricing and availability
The D2 Plus Matter is listed on Amazon at $159.99. The D2L Lever ships later at $179.99. Both fall in the mid-tier band occupied by Ultraloq, Schlage Encode Plus, and the Aqara U-series.
Verdict
Buy if Thread-native integration into an existing Apple, Google, or Alexa mesh is the priority and local-only operation is required. Skip if independent cybersecurity attestation or transparent secure-element documentation is non-negotiable. The 0.3-second unlock claim is unverified outside TCL's own test conditions.
