The YHJ BL03 is a premium biometric smart lock purpose-built for glass doors — fingerprint, IC card, PIN keypad, remote control & Tuya app. No-drill clamp-on installation. Perfect for offices, homes, and boutiques.
Key Features
Biometric Fingerprint Sensor
The BL03's semiconductor-grade fingerprint scanner reads your unique print in milliseconds — accurate, tamper-resistant, and effortless. Store up to 100 fingerprints for family members, colleagues, or trusted guests, all manageable from the Tuya app.
💳 IC Card Access
Comes with IC access cards for a quick tap-to-open experience. Cards are easily issued, suspended, or revoked remotely — perfect for offices, short-let hosts, and shared access environments.
🔢 Anti-Peeping Touchscreen Keypad
The backlit touchscreen keypad supports virtual password protection: enter random extra digits before or after your real PIN and the lock still opens — anyone watching cannot determine your actual code.
📡 Wireless Remote Control Included
The BL03 ships with a dedicated wireless remote fob for one-click locking and unlocking from a distance — ideal for accessibility, vehicles nearby, or simply not wanting to reach for your phone.
📱 Tuya Smart App — Full Remote Control
Connect via Bluetooth and 2.4GHz Wi-Fi to the Tuya Smart App and manage everything from your phone:
Lock or unlock from anywhere in the world
Issue and revoke temporary access codes for guests
View complete real-time door access logs
Receive instant push notifications on every entry event
Manage fingerprints, cards, and PINs remotely
🏢 No-Drill Glass Door Installation
The BL03 uses a precision clamp-on mounting system — no drilling, no cutting, no damage to your glass. It clamps securely to both frameless glass (10–12mm) and framed glass doors (up to 120mm), and can be repositioned if needed.
🖤 Ultra-Slim All-Black Design
At under 22mm thin, the BL03's matte black body with its polished touchscreen face is designed to complement the transparency of glass rather than interrupt it. It is as much a design object as it is a lock.
🔋 USB Emergency Power Backup
Should the internal battery run low, any USB power bank connected to the USB backup port supplies enough emergency power to unlock — you are never stranded outside your own door.
