About
TCL's D2 Pro unlocks by reading the vein pattern in your palm, a biometric that is harder to spoof than a fingerprint and works without touching a sensor. The 2026 revision is the notable one: TCL released a version that works with any major smart home ecosystem rather than locking buyers into one platform. A good choice if you want keyless, phone-free entry.
Pros
- +Palm vein scanning is fast and hard to spoof
- +Works with any major ecosystem, not just one
- +No phone needed to unlock
- +Matter support
Cons
- −Replaces the whole lock, so not renter-friendly
- −Biometric hardware raises the price
- −TCL has a shorter track record in locks than Yale or Schlage
