Under the bright lights and buzzing crowds of CES 2026 in Las Vegas, where every year feels like a race toward tomorrow’s conveniences, one device stopped many visitors in their tracks — not with spectacle, but with a hint of permanence. Lockin’s latest smart lock — the V7 Max — was on display as a feature-rich door security solution that seems to reframe what it means for a smart lock to be “everlasting.” Conceived by a company best known for vein-recognition security and biometric access, this new combo pairs a mortise smart lock with a video doorbell and an elusive worry-free power system that might just be the peak of the show for practical home tech.
At the heart of the V7 Max is Lockin’s AuraCharge™ optical wireless charging technology, which eliminates the nagging concern of dead batteries that many smart lock owners know all too well. Instead of replacing batteries or relying on solar panels, a small indoor transmitter emits eye-safe optical energy to power the lock continuously from up to four meters away. That means the lock’s lithium battery is constantly topped up, theoretically without human intervention or maintenance. It’s a quiet but profound tweak to the everyday worry about lost access due to drained cells.
This isn’t just a door gadget with new hardware — it’s a security device with multiple biometric brains. The V7 Max integrates finger vein, palm vein, and 3D facial recognition to verify identities, a suite of technologies designed to make unauthorized entry extremely difficult. The use of vein patterns, beneath the skin and unique to individuals, serves as a particularly resilient layer of security that resists replication far better than simple fingerprints or codes.
Beyond access, the lock doubles as a video doorbell camera with dual high-definition lenses, offering both surveillance and interaction. Lockin’s accompanying AI — branded LockinAI® — can handle tasks like recognizing package deliveries, alerting homeowners to unusual motion, and even indexing recorded video for quick search. The integration doesn’t stop there: the system is compatible with major smart home ecosystems such as Google, Apple, Amazon, and Samsung via the Matter standard, letting users tie their entryway security into an existing connected home setup.
Design details matter here as well. Crafted with influence from Hartmut Esslinger, famed for Apple’s iconic design language, the V7 Max balances sleek modern lines with robust functionality. Dual touchscreen panels — one outside, one inside — make interaction intuitive without detracting from the door’s overall aesthetic. It’s a blend of thoughtful engineering and considered form.
Taken together, Lockin’s new smart lock strikes an intriguing balance between convenience, security, and peace of mind. By addressing common frustrations — dead batteries, fragile security, disconnected devices — with integrated solutions, the V7 Max suggests a future where smart home technology is not just smart, but seamlessly dependable. Whether that future arrives in every household depends on price and user adoption, but at CES 2026, this door lock quietly stole its share of the spotlight.
