Review: Sifely Keyless-Entry Fingerprint Smart Door Lock (Silver) – A Flexible, Secure Upgrade for Modern Homes

As smart home devices become increasingly popular, smart door locks are gaining traction as one of the most practical investments for both security and convenience. The Sifely Keyless-Entry Fingerprint Smart Door Lock offers a sleek, modern solution for managing access to your home, office, or private room—without needing a traditional key.

This review provides a comprehensive, unbiased look at the features, performance, pros, and cons of the Sifely Smart Lock to help you decide if it's the right fit for your security needs.

🔧 Overview & Design

The Sifely Smart Lock is designed to replace a traditional door knob and bring biometric security features into your everyday environment. Finished in sleek silver, it offers a clean and modern look that complements both residential and commercial interiors.

The lock integrates five different unlocking methods: fingerprint, passcode, smartphone app, fob key, and traditional key. This gives users plenty of flexibility, which is ideal for families, Airbnb hosts, small businesses, or anyone managing multiple users.

It fits most standard U.S. doors (left/right handle reversible) and is marketed as suitable for both interior and exterior use, including front entry doors and bedroom doors.

🔑 Key Features

1. Biometric Fingerprint Recognition

The highlight feature is the fingerprint scanner, which can recognize and unlock the door in under one second. Sifely claims a 98% accuracy rate, and in testing, fingerprint entry was generally fast and reliable after proper setup. The scanner stores up to 100 fingerprints, making it useful for multi-user households or guest properties.

It’s important to note that the scanner works best with clean, dry fingers. Dust, water, or rough skin can sometimes interfere with recognition, though this is common across most biometric devices.

2. Multiple Access Options

In addition to fingerprint access, the Sifely lock can be unlocked via:

• Numeric passcode (entered on a touchscreen keypad)

• Sifely app (via Bluetooth)

• Fob key (a small RFID device)

• Mechanical key (backup access in case of tech failure)

Having five unlocking methods makes this lock extremely versatile. The app is compatible with both iOS and Android platforms and allows for remote access, access log tracking, temporary code creation, and more. For Wi-Fi access, a separate Sifely Gateway hub is required (sold separately).

3. Sifely App Features

The app provides control over access management, including:

• Generating one-time or time-limited passcodes

• Viewing access logs (who entered and when)

• Lock/unlock the door via Bluetooth

• Receive real-time alerts (only with Wi-Fi Gateway)

It’s particularly useful for Airbnb hosts, property managers, or those needing flexible control over who can access a door and when.

4. Battery Life and Power

The lock operates on 4 AA batteries, with a typical battery life of 6 to 12 months, depending on usage. The app provides low-battery alerts. In case the battery dies, users can:

• Use the mechanical key to unlock

• Use a USB-C emergency power port to temporarily power the lock from an external battery pack

This dual redundancy adds a critical level of reliability for tech-based locks.

5. Installation

Installation is DIY-friendly and takes approximately 15–30 minutes for someone with basic tools and skills. It fits most standard single-cylinder deadbolts and comes with clear instructions. There’s also video support via the Sifely website and customer service.

No hardwiring is required, and all components are powered by battery, which simplifies setup.

🛡️ Security & Durability

Sifely Smart Locks use AES128 encryption to secure digital data, adding a strong layer of protection. In terms of physical build, the metal construction feels durable and sturdy, suitable for both indoor and outdoor use. However, it lacks IP weatherproof certification, so it may not be ideal for doors exposed directly to harsh elements like rain or snow without additional covering.

While it's secure for general household use, it may not meet commercial-grade or high-security standards required for some institutions or environments with elevated risk.

💬 User Experience

Most users report a positive experience with the Sifely Smart Lock, particularly appreciating the fast fingerprint recognition, convenient code-sharing, and easy installation.

That said, some users experience inconsistencies with:

• App connectivity, especially over Bluetooth when standing at a distance

• Fingerprint misreads, particularly with wet or worn fingers

• Battery life variance, depending on usage patterns

The Wi-Fi Gateway, which enables remote access, is a separate purchase—some users expected this to be included, so that’s important to note upfront.

🧑‍💻 Use Cases

This lock is ideal for:

• Families who want to avoid lost keys

• Airbnb or short-term rental hosts who want to share temporary access

• Home offices or private rooms needing restricted access

• Elderly users (the fingerprint function is quicker than remembering a passcode)

However, it might be less ideal for outdoor gates or doors heavily exposed to extreme weather, unless shielded or used with additional sealing.

✅ Pros

• Five unlocking methods (fingerprint, app, code, fob, mechanical key)

• Fast fingerprint scanner with good accuracy

• User-friendly mobile app (iOS and Android)

• Remote access & logs via optional Wi-Fi Gateway

• Easy DIY installation with reversible handle

• Emergency power & key access backup

• Ideal for Airbnb, rentals, family homes

• Stylish silver design fits modern decor

⚠️ Cons

• Wi-Fi Gateway sold separately

• App can be buggy with Bluetooth pairing delays

• Fingerprint sensor may fail with dirty/wet fingers

• Not fully weatherproof for direct outdoor exposure

• Battery life varies based on usage and settings

• Initial setup and app interface may be confusing to some users

⚖️ Final Verdict

The Sifely Keyless-Entry Fingerprint Smart Door Lock is a solid, well-rounded product that balances modern technology, flexible access options, and ease of use. Whether you're looking to upgrade your home security, simplify entry for multiple users, or manage an Airbnb property more efficiently, this smart lock offers great value for its price point.

Though not without its flaws—particularly in Bluetooth consistency and lack of Wi-Fi without a separate gateway—the Sifely Smart Lock is a dependable and affordable choice in the ever-expanding smart home security market.

It’s not the best fit for high-security commercial settings or full outdoor exposure, but for residential use, it checks most boxes very well.
