This is a K1 smart knob. It can be opened with another K1 smart knob... The backup cylinder looks like a simple wafer lock. Don't expect electronic toymakers like these to secure your house.
TCL has launched a new K1 smart door knob globally. The company's new smart home accessory features 0.3-second fingerprint recognition, passage mode, private mode, and an aerospace-grade aluminum build. On top of that, it offers app-based controls and up to 12 months of battery life.
