Overview
The Sifely Keyless Entry Smart Lock combines biometric fingerprint scanning, digital passcodes, and smartphone app controls to offer a comprehensive smart lock solution. Designed for residential and small business use, this lock is easy to install and packed with modern access features. Whether you’re managing rental properties or upgrading home security, this smart lock promises convenient access with an emphasis on control, customization, and safety. In this review, we explore the lock’s key features, real-world performance, ease of setup, and who it’s best suited for in 2025.
Installation Process
The Sifely Smart Lock boasts a DIY-friendly installation that takes approximately 20–30 minutes. It fits most standard doors (35mm to 53mm thick) and includes all the hardware and instructions needed for setup. No drilling is required if replacing a standard deadbolt, making it ideal for renters or frequent movers.
Everything comes clearly labeled, including the mounting plate, interior mechanism, and handle. Installation can be done with just a screwdriver, and pairing with the Sifely app is intuitive, guiding you through each step with prompts and visuals.
Fingerprint & Daily Use Performance
The fingerprint scanner on the Sifely Smart Lock is fast and responsive, typically unlocking within 0.5 seconds. It supports up to 150 unique fingerprints, making it suitable for shared properties or larger families. Recognition accuracy is high, although very wet or dirty fingers may require a second try.
Users can also access the lock via a passcode, fob, the mobile app, or a backup mechanical key. This range of access options provides flexibility for different scenarios, from kids getting home from school to granting entry to temporary guests.
Smartphone App and Remote Access
The Sifely app offers excellent control, allowing users to create and manage access codes, view unlock logs, and receive entry alerts. It supports remote access via the optional Sifely Wi-Fi Gateway (sold separately), enabling control from anywhere.
You can generate permanent, timed, or one-time codes—especially useful for Airbnb hosts or property managers. Without the Wi-Fi Gateway, Bluetooth is the primary connection method with a range of about 10 meters.
Build Quality and Aesthetics
The Sifely lock features a sleek, modern design with a durable zinc alloy body and weather-resistant finish. Available in black, silver, and bronze finishes, it blends well with various door styles. The touchscreen keypad is bright and easy to read, even in low light, and the overall feel is robust without being bulky.
Battery Performance
Powered by 4 AA batteries, the lock lasts approximately 6–10 months depending on use. Battery level monitoring is available in the app, and low-battery alerts help prevent lockouts. If batteries deplete completely, users can recharge the lock temporarily via a USB-C port or use the physical key override.
Security and Encryption
The lock uses AES 128-bit encryption to secure communication between the lock and your smartphone. Biometric data is stored locally for privacy protection. There’s also an automatic lock function and a privacy mode that disables all digital entries until manually overridden, ideal for nighttime or travel scenarios.

How It Compares
Compared to similarly priced locks like the Ultraloq U-Bolt or Yale Assure SL, the Sifely Smart Lock stands out for its wide variety of access methods and lower cost of entry. While others offer smart assistant integration, Sifely’s fingerprint and code capabilities make it ideal for users prioritizing security and ease of access over voice control or cloud dependency.
Final Verdict
The Sifely Keyless Entry Smart Lock is an excellent value for homeowners and property managers seeking a modern, flexible access solution. Its fingerprint scanner, robust app features, and simple installation process make it ideal for those who want high-tech convenience without recurring subscription costs. While smart assistant fans may need to look elsewhere, the Sifely lock shines for what it offers at this price point.
