Engineered for boutique hotels, upscale apartments, commercial offices, and modern residential interiors, the GM3 Split Biometric Smart Lever Lock combines minimalist split-rose architectural styling with versatile keyless access. Featuring an integrated biometric fingerprint sensor directly on the lever handle, an illuminated touchscreen passcode keypad, and Bluetooth mobile app management, it delivers effortless, secure entry while maintaining a clean, contemporary door profile.

Multiple Keyless Access Methods

• One-Touch Biometric Fingerprint: Semiconductor biometric scanner embedded directly in the ergonomic handle axis unlocks the door in under 0.3 seconds.
• Anti-Peep Touchscreen Keypad: Backlit digital keypad supports anti-peeping phantom PIN codes (enter random digits before/after your actual PIN) to protect against onlookers.
• Bluetooth Mobile App Control: Compatible with Tuya Smart / TTlock apps for seamless Bluetooth unlocking, eKey sharing, temporary guest passcodes, and real-time access logs.
• Mechanical Key Backup: Concealed lower rosette keyway provides emergency access via traditional high-security physical keys.
• Passage Mode: Easily toggle continuous free-passage mode during office business hours, family gatherings, or high-traffic events.
