Lockin

Lockin is an online-only smart-lock specialist that sells retrofit deadbolts, lever sets, padlocks and cabinet locks priced USD 89-299, plus subscription cloud-storage plans at $2-5 per month. The catalogue is split into budget Bluetooth models, mid-range Wi-Fi locks and a premium fingerprint/video-doorbell combo unit; everything ships direct from Shenzhen to North America, Europe and Australia. The brand’s core pitch is “5-minute DIY install, no hub needed”: every lock auto-calibrates to existing door geometry and pairs through a single QR code. Notable lines include the G30 gateway-free deadbolt (2022 Red-Dot winner) and the L60 video lock that streams 1080p footage over eSIM when Wi-Fi drops—both perennial best-sellers on Amazon’s Smart-Lock leaderboard. Primary buyers are 25-45-year-old renters and Airbnb hosts who want keyless access without drilling or landlord disputes; the app issues time-boxed e-keys and syncs with booking calendars. Value drivers are convenience, clean industrial styling and the ability to remove the lock and reinstall in a new apartment within minutes. Lockin competes in the crowded sub-$300 smart-lock segment against legacy deadbolt makers pivoting to “smart” and crowdfunded gadget brands. It differentiates through a hub-free architecture that cuts hardware cost, a software layer optimized for short-term-rental turnover, and global firmware that supports both Schlage and Euro cylinder spacing out of the box.
