HISMART Tuya Smart Electronic Cylinder Lock with Fingerprint, Mifare Card, App Control, and Mechanical Key

Traditional locks leave you fumbling for keys and worrying about lost copies. The HISMART Electronic Cylinder replaces your standard Euro profile cylinder with a smart, keyless entry system that combines fingerprint recognition, Mifare card access, and remote control via the Tuya Smart app. It installs in minutes without drilling, keeping your existing door hardware intact.
