Before smart locks, locking and unlocking the door was a daily hassle. I'd dig through my bag, trying to find my keys, then struggle to fit them into the lock—especially when my hands were full. Getting the key perfectly into the lock felt like an unnecessary challenge. And even after finally locking up, another worry kicked in: Did I actually lock the door? More than once, I had to turn back just to check.

I couldn't help but think—why do we even need keys? What if doors could lock and unlock effortlessly, without the hassle, without the doubt? And what if I could check what's happening at my door anytime, right from my phone?That's why I dreamed of a lock that could unlock effortlessly, lock automatically, and let me check my home anytime.

Today, Lockin's latest innovation—palm vein recognition—delivers the ultimate in security and convenience. Paired with local AI algorithm monitoring, a 180° ultra-wide HD camera, local storage, and solar charging, we've created a smart lock that's intuitive, reliable, and designed to simplify your life.

Because we believe a smart home doesn't start with the appliances inside—it starts at the door.
