Looking Beyond the Locstar Fingerprint Door Lock? 6 Alternatives Worth a Look

How each alternative compares

Evanshow Biometric Fingerprint Door Knob

The Evanshow Biometric Fingerprint Door Knob expands your access options significantly. While the Locstar K66 relies solely on fingerprints, this unit supports keypad codes, keys, key cards, and fingerprints. You gain flexibility if you frequently forget your biometric registration or need temporary access for guests. The included hardware is a knob, matching the Locstar form factor. However, it is slightly wider at 5.5 inches compared to the Locstar’s 2.8 inches. This extra width may not fit standard interior door preparations. If you need multiple entry methods and have a wider door, this is a practical upgrade. You sacrifice the simple manual-locking privacy feature of the Locstar for broader access control.

KLLOQUE Fingerprint Smart Door Knob

The KLLOQUE Fingerprint Smart Door Knob offers a matte silver finish instead of the Locstar’s black. It matches the Locstar in using only fingerprint access for entry. The KLLOQUE model is longer at 9 inches, which might suit taller door preparations better than the 11.8-inch Locstar. It lacks the explicit backup key feature mentioned for the Locstar, relying instead on app management via local Bluetooth. This makes it ideal for bedrooms or bathrooms where you do not need remote app access. You get a simpler, app-free exterior experience if you prefer local control. The narrower width of 3 inches fits standard bore holes well. Choose this if you want a sleek, silver aesthetic without the complexity of remote management.

DREMUSOUD Biometric Smart Door Handle

The DREMUSOUD Biometric Smart Door Handle differs by using a handle instead of a knob. This lever design may be easier for users with limited hand strength. It adds a keypad to the fingerprint sensor, giving you more entry options than the Locstar’s fingerprint-only approach. The unit is significantly taller at 10 inches, requiring a different door preparation. It is wider at 3 inches. This model suits homes needing app control and multiple access methods. You trade the compact knob size for a more robust lever mechanism. If you prefer a traditional lever look and want to enter via code or fingerprint, this is a strong alternative. The larger sensor size may improve recognition speed in low light.

FDFDTO Rechargeable Fingerprint Door Handle

The FDFDTO Rechargeable Fingerprint Door Handle combines a keypad and fingerprint sensor, offering more entry methods than the Locstar’s single fingerprint approach. It uses a handle design, which differs from the Locstar’s knob. The unit is 9.7 inches long, fitting standard door heights. It supports app management for guest access, similar to the Locstar. However, the handle format changes the door’s aesthetic and functionality. You gain the convenience of a numeric code for guests who may not have registered fingerprints. The black finish matches the Locstar. Choose this if you need both codes and biometrics with a lever handle. It is well-suited for offices or bedrooms where quick, flexible entry is prioritized over simple manual locking.

Buoan Biometric Fingerprint Door Knob

The Buoan Biometric Fingerprint Door Knob focuses on speed and simplicity. It matches the Locstar’s 0.3-second entry time but adds auto-locking, which the Locstar lacks. This means you do not need to manually press the interior button to secure the door. It uses only fingerprint access, keeping the exterior clean. The unit is slightly shorter at 7.4 inches. It lacks app control, making it a purely local device. This is ideal if you want quick entry without managing an app or worrying about battery connectivity. You trade smart features for reliable, automatic security. The black knob design is familiar. Pick this if you prioritize hassle-free operation and automatic locking over remote management or manual privacy control.

ThorBolt Fingerprint Keypad Door Knob

The ThorBolt Fingerprint Keypad Door Knob offers both keypad and fingerprint access, unlike the Locstar’s fingerprint-only entry. It features a passage mode switch, allowing you to keep the door unlocked for through-traffic without locking or unlocking. This is useful for home offices or shared spaces. The unit is 6.5 inches long, shorter than the Locstar. It is app-free, relying on local biometric and code entry. You gain flexibility with codes and a passage mode but lose the app management features of the Locstar. The black knob fits standard doors. Choose this if you need quick biometric entry and occasional code access without the complexity of an app. It is best for interior doors where you want simple, reliable control.
