Sifely vs LINGDU Lock Specs
Connectivity
The LINGDU WL01 features built-in Wi-Fi, allowing it to connect directly to your home network. This enables remote access and management through the app without any additional hardware. You can generate codes and check logs from anywhere. The Sifely Fingerprint Smart Lock relies on Bluetooth for local connectivity. To unlock the door remotely, you must purchase the optional Sifely WiFi Gateway separately. Without this extra device, remote features are unavailable. For users who want immediate remote capabilities out of the box, the LINGDU approach is more straightforward.
Power Source
The LINGDU WL01 is powered by eight AA batteries. The manufacturer states that its ultra-low energy consumption provides up to eight months of battery life. This provides a clear expectation for maintenance intervals. The Sifely Fingerprint Smart Lock does not list its specific power source or battery capacity in the provided specifications. While most locks in this category use batteries, the lack of detail makes it difficult to compare longevity. You cannot determine how often you need to replace batteries for the Sifely model based on the current data.
Build Quality
The LINGDU WL01 holds an ANSI Grade 3 certification, which indicates a standard for mechanical reliability and durability. It also carries an IP54 waterproof rating, protecting it against rain and dust in harsh outdoor conditions. These specs suggest a focus on long-term outdoor performance. The Sifely Fingerprint Smart Lock does not list any ANSI grade or IP rating in the provided data. Without these specific durability metrics, you have less information regarding its resistance to weather or forced entry compared to the certified LINGDU model.
Access Methods
Both locks offer multiple ways to enter your home. The LINGDU WL01 supports fingerprints, passcodes, app control, voice commands, and a mechanical key. It can store up to 50 unique fingerprints and 50 custom passcodes. The Sifely Fingerprint Smart Lock unlocks via fingerprint, keypad, app, FOB, or key. The Sifely model includes a physical FOB, which the LINGDU does not explicitly list as a standard access method. Both support voice control via Alexa and Google Assistant. The Sifely offers a physical token option, while the LINGDU offers higher capacity for digital credentials.
Smart Home Compatibility
Both the Sifely Fingerprint Smart Lock and the LINGDU WL01 integrate with major voice assistants. You can use Alexa or Google Assistant to control both locks. However, the Sifely requires the optional WiFi Gateway to enable voice control and remote features. The LINGDU connects directly to your network, so voice commands work immediately without extra hardware. If you already have a smart home ecosystem, the LINGDU integrates more seamlessly. The Sifely requires an additional purchase to unlock its full smart home potential.
Included Hardware
Both locks come with a handle included in the box. The Sifely Fingerprint Smart Lock is described as having a handle and is designed for DIY installation on most standard doors. The LINGDU WL01 is also listed with a handle but is specifically marketed as a deadbolt lock set. The Sifely handle is reversible for left or right-handed doors. The LINGDU data does not specify handle reversibility. Both provide the necessary hardware for installation, but the Sifely explicitly mentions compatibility with standard door configurations.
Choose the Right Smart Lock for You
Renters needing remote guest codes without extra hardware
The LINGDU WL01 includes built-in Wi-Fi, so you do not need to buy a separate gateway for remote access. You can generate temporary codes and view logs from anywhere using the app. This direct connection simplifies management for Airbnb hosts or landlords who need to grant and revoke access instantly without additional equipment.
Users wanting voice control and auto-lock convenience
LINGDU supports hands-free voice control via Alexa or Google Assistant and features an auto-lock function. This deadbolt secures itself after a set time, reducing the risk of leaving the door open. The matte black finish and IP54 waterproof rating also make it suitable for harsh outdoor conditions on your front door.
Homeowners preferring Bluetooth stability and FOB access
The Sifely lock relies on Bluetooth for local app control, which works reliably without internet dependency. It also supports a physical FOB, offering an alternative to keys or phones. This model is ideal if you prefer a straightforward setup with reversible handles and do not require the auto-lock features found in the Wi-Fi model.

Frequently asked questions
Does the Sifely Fingerprint Smart Lock require a separate gateway for remote access?
Yes, the Sifely S model does not include built-in Wi-Fi. You need to purchase an optional gateway to enable remote features like app control and voice commands. Without this add-on, you can only use local access methods such as the keypad or fingerprint scanner directly at the door.
Can I control the LINGDU WL01 lock with my voice?
Yes, the LINGDU WL01 integrates with both Alexa and Google Assistant. You can use voice commands to lock or unlock the door when you are home or away. This connectivity works because the lock has built-in Wi-Fi, allowing it to communicate directly with smart home platforms without extra hardware.
Which smart lock is better for rental properties?
The LINGDU WL01 is ideal for rentals due to its high user capacity and direct Wi-Fi connectivity. You can generate temporary codes for guests or maintenance staff from anywhere.

What access methods does the Sifely Fingerprint Smart Lock support?
The Sifely S supports keypad entry and fingerprint scanning. You can enter a code or place your finger on the sensor to unlock the door. It does not list app control as a native feature without the optional gateway, so your primary access relies on these two physical methods.

The data provided lists the LINGDU WL01 specifically in matte black. There is no information about other color options for this model. If you require a different finish, you may need to check other listings or contact the manufacturer, as the current specifications only confirm the matte black variant.
How heavy is the Sifely Fingerprint Smart Lock with Handle?
The Sifely S weighs 6 pounds. It measures 3 inches in width, 1.12 inches in height, and 7 inches in length. This weight reflects the solid construction of the knob-style handle, which is designed for standard doors. The size ensures it fits most residential door frames without modification.

Can I use the Sifely lock with Google Home?
