The Waterproof Narrow Stile Smart Door Lock with Handle-Integrated Fingerprint & Keypad is purpose-built for narrow frame profiles, aluminum sliding doors, sunroom enclosures, and outdoor courtyard fence gates. Featuring an innovative handle architecture that embeds both a semiconductor biometric fingerprint scanner and a backlit touchscreen keypad directly onto the lever handle, it eliminates bulky surface plates while maintaining an ultra-slim 35mm escutcheon. Available in both single-sided entry and dual-sided access configurations, the double-sided model enforces authorized biometric verification on both the exterior and interior, preventing unauthorized entry through fence railings and gate grilles.

Key Features

• Handle-Integrated Biometric Scanner & Keypad: Ergonomically embeds the semiconductor fingerprint sensor and backlit numeric touch keypad directly into the lever handle, enabling intuitive one-handed verification and unlocking.
• Single & Double-Sided Dual-Access Configurations: Offers standard single-sided entry as well as double-sided models requiring fingerprint or passcode authentication from both sides, ideal for outdoor security gates, pool fences, and courtyard railings.
• Ultra-Slim Narrow Stile Architecture: Designed with a minimalist slimline escutcheon engineered specifically for narrow frame profiles, thermal break aluminum doors, and sliding patio doors where standard wide smart locks cannot fit.
• All-Weather IP65 Outdoor Resilience: Fully sealed against driving rain, direct UV sunlight, humidity, and extreme temperature fluctuations (-20°C to 60°C), ensuring reliable outdoor gate performance.
• Tuya / TTLock Smart App Connectivity: Built-in Bluetooth with optional WiFi gateway integration enables mobile app management, generation of time-sensitive visitor passcodes, entry audit tracking, and passage mode scheduling.
• Passage Mode (Always-Open Function): Easily toggle to passage mode during social gatherings, deliveries, or commercial business hours to allow unrestricted ingress and egress without repeated unlocking.
• Heavy-Duty Stainless Steel Narrow Mortise: Equipped with an anti-saw stainless steel hook latch or flat deadbolt mortise engineered for high shear strength and forced-entry deterrence.
• Dual Emergency Failsafes: Features a concealed bottom mechanical keyhole with Class C lock cylinder and an external USB emergency power jump interface for complete peace of mind.
