Product Overview

The Sifely Smart Door Lock is a modern, keyless-entry deadbolt designed to transform how you secure and access your home. Built for front doors, entry doors, and exterior doors, this advanced digital lock integrates electronic fingerprint recognition with a responsive numeric keypad, offering both convenience and peace of mind. Whether you’re managing access for family members, guests, or service providers, the lock supports up to 150 unique user codes and 100 fingerprints—making it ideal for households or rental properties where multiple people need reliable, touch-free entry. Real-time activity tracking via a dedicated mobile app lets you monitor every unlock event, while active feedback ensures you always know your door’s status. With low battery alerts and durable construction, this smart deadbolt delivers dependable performance without compromising on security.

Key Features

• Keyless Entry via Code: Create and manage up to 150 access codes tailored to your lifestyle—Permanent, Timed, Recurring, or Custom codes. This flexibility allows you to grant temporary access for guests or service providers without physical keys. Most code types can be generated and managed remotely through the companion app, though custom codes require the optional SamTechT Gateway for full functionality.
• Fingerprint Unlock Technology: Enjoy fast, hygienic entry with a high-speed optical sensor that recognizes fingerprints in just 0.3 seconds. The lock stores up to 100 unique fingerprints using a 508 DPI resolution sensor, achieving a 99.99% recognition accuracy. Ideal for families or individuals who prioritize quick, contactless access.
• Remote Access Control & Activity Tracking: Monitor all entry events through the intuitive mobile app, including timestamps, user IDs, and lock status changes. This feature enhances accountability and security, especially useful in shared living spaces or when managing short-term renters. You can view real-time logs and receive instant notifications whenever someone unlocks the door.
• Real-Time Active Feedback: Stay informed with clear audio and visual cues—such as “Unlocked,” “Locked,” and “Battery Level Low”—so you never second-guess your door’s state. These confirmations reduce uncertainty and help prevent accidental lockouts or security lapses.
• Low Battery Alert System: Proactive notifications warn you when battery levels are running low, giving you ample time to replace them before the lock powers down unexpectedly. This ensures uninterrupted operation and prevents being stranded outside due to depleted batteries.

Benefits & Use Cases

This smart deadbolt is engineered for homeowners, property managers, and renters who value both security and convenience. It excels in multi-occupancy environments such as family homes, vacation rentals, or Airbnb units, where trusted guests or maintenance personnel frequently enter. The ability to generate timed or recurring access codes eliminates the need to share physical keys or rekey locks after each use—ideal for seasonal tenants or cleaning services.

For daily household use, the fingerprint unlock provides a seamless, hygienic alternative to traditional keys, especially beneficial during cold and flu season or for individuals with mobility challenges. The extensive code storage supports permanent residents alongside occasional visitors, while the app-based activity log adds an extra layer of oversight. You’ll always know who accessed your home and when, enhancing safety and reducing concerns about unauthorized entry.

Homeowners appreciate the peace of mind that comes with real-time feedback and low battery warnings, ensuring they’re never caught off guard by a dead lockout. The nickel finish not only complements modern exterior designs but also resists wear and weathering, maintaining appearance and function over time.
