Who it fits
Good fit for

Families benefit from the 0.3-second fingerprint unlock speed. Rental properties gain from the app’s ability to create codes and view logs.

Sifely S Key Specs Explained
Connectivity: Bluetooth
This lock connects directly to your phone via Bluetooth. You do not need a WiFi hub for basic operation. This reduces setup complexity and potential points of failure. It is ideal for renters who cannot modify wiring. You can unlock the door when your phone is nearby. Compare this to WiFi models that require constant internet connectivity for remote access.
Access Method: Keypad, Fingerprint
You can enter a code or use your fingerprint to unlock the door. The fingerprint sensor takes 0.3 seconds to recognize your print. This speed is faster than most standard keypads. It is convenient for families with children who forget codes. You can also share temporary codes with guests. This dual method offers flexibility if your battery dies or your phone is lost.
Smart Home Compatibility: Alexa, Google Assistant
The lock works with Amazon Alexa and Google Assistant. You can use voice commands to lock or check the door status. This adds convenience if you are already using these assistants. It allows for hands-free operation when your hands are full. You do not need a separate smart home hub for this compatibility. Compare this to locks that only support proprietary apps without voice integration.
Weight: 1 pounds
The unit weighs one pound. This is a lightweight design for a deadbolt lock. It may be easier to install than heavier metal alternatives. However, it might feel less substantial than heavy-duty commercial locks. Consider this weight if you are mounting it on a hollow core door. Heavier locks often provide more resistance against forced entry attempts.
Design and Build Overview
The Sifely S presents a straightforward exterior profile. According to the listing, the unit measures 7 inches in height, 3 inches in width, and 1.2 inches in length. It weighs approximately 1 pound. These dimensions suggest a compact footprint suitable for standard residential front doors. The finish is black, which helps it blend with most exterior trim styles without drawing unnecessary attention.
The hardware includes a handle and a heavy-duty deadbolt knob. This physical configuration provides a traditional feel while integrating modern keyless entry. You get both a keypad and a fingerprint sensor for access. The fingerprint sensor is positioned for easy reach. The keypad allows for passcode entry, offering flexibility if your hands are full. The lock supports multiple unlock methods, including app control, FOBs, and mechanical keys for backup.
Connectivity relies on Bluetooth rather than WiFi. This design choice simplifies installation since you do not need to connect to a home network for local access. The lock works with Amazon Alexa and Google Assistant for voice commands. The overall build focuses on durability and ease of use. The materials are described as heavy-duty, aiming to withstand daily wear. This construction makes it a practical option for homeowners and rental properties who need reliable, keyless entry without complex wiring.
Setup and Everyday Use Guide
Setting up this lock relies on your smartphone. The Bluetooth connection allows direct pairing without a separate WiFi hub. This simplifies installation for renters or homeowners who want to avoid wiring changes. You download the companion app to manage the device. The interface lets you create passcodes, view access logs, and add or remove users. This digital management replaces physical key distribution. For daily entry, the lock offers multiple methods. The fingerprint sensor recognizes your print in 0.3 seconds. This speed ensures quick entry for families and frequent guests. You can also use the keypad, the app, a FOB, or a mechanical key if needed. The system supports auto-locking, which secures the door behind you without manual intervention.

Before You Buy This Lock
Before purchasing the Sifely S, consider your existing smart home setup. It works with Alexa and Google Assistant, but you must verify your specific devices support these commands.
