Who it fits

Key specs for Lockly Secure Plus

Access Methods: Keypad, fingerprint, key

You can enter your home using a code, your fingerprint, or a physical key. This variety ensures you have a backup if your battery dies or your finger is wet. It suits renters and homeowners who want reliable, keyless entry without relying on a single method. Compare this to locks that only offer app control, which can fail if your phone is lost.

Fingerprint Capacity: 99 fingerprints

The lock stores up to 99 unique fingerprints. This capacity covers most families and frequent guests. You can assign different prints to different users for easy tracking. It is ideal for households with multiple adults and older children. When shopping, check if other locks offer fewer slots, which might require deleting old users to add new ones.

Size: Right Fingerprint Edition

This specific model is designed for right-hand doors. The fingerprint sensor is positioned on the right side of the interior unit. You must verify your door handedness before buying to ensure proper fit. An incorrect match means the lock will not function correctly. Compare this with universal models that allow sensor rotation for left or right doors.

Color: Matte Black

The finish is a non-reflective black that resists fingerprints and smudges. It provides a modern look that blends with most exterior door styles. The matte texture hides minor scratches better than glossy finishes. Choose this if you prefer a sleek, low-maintenance appearance. Check other options if your door frame is white or wood, as contrast may be desired.

Design and build specs

According to the listing, the Lockly Secure Plus Biometric Deadbolt is available in a Matte Black finish. This color choice is practical for outdoor exposure, as it tends to mask dust and minor scratches better than lighter tones. You get a Right Fingerprint Edition, which determines the hand orientation of the lock body. This matters for installation, as it must align with your door’s handedness to fit properly. The listing specifies a weight of 1 pound. This light weight suggests the internal components are compact, which may simplify handling during setup but requires careful mounting to ensure stability.

The physical dimensions are 3.15 inches in width, 4.49 inches in height, and 7.36 inches in length. These measurements define the footprint on your door’s interior and exterior faces. You need to verify that your door’s stile can accommodate this width without interfering with existing hardware or strike plates. The length extends into the door edge, securing the mechanism firmly. The matte black coating covers these metal parts, offering a uniform look that blends with modern door designs.

Controls include the patented PIN Genie keypad and the 3D biometric sensor. The keypad layout uses virtual buttons that change positions, adding a layer of security against code observation. The fingerprint sensor is positioned for natural access. You should check your door’s thickness to ensure the 7.36-inch length is sufficient for a secure fit. The design prioritizes functionality over ornamentation, focusing on secure entry rather than decorative appeal.

Setup and everyday use

Installation relies on common household tools, guided by a detailed manual provided by the manufacturer. This approach keeps the setup process straightforward for most users. You do not need specialized equipment or professional assistance to mount the unit on your door.

For daily operation, the lock offers multiple access methods. You can use the patented PIN Genie keypad, which features virtual buttons that change position after each use. This design prevents observers from guessing your code by watching finger movements. Alternatively, you can use the 3D biometric fingerprint sensor. It recognizes your print in 0.3 seconds and unlocks the door in 0.5 seconds. The sensor stores up to 99 fingerprints, allowing family members or trusted guests quick entry.

You can also grant offline access codes for specific time periods. These codes work without Wi-Fi or internet connectivity, ensuring access even if your network is down. A physical key serves as a reliable backup if the battery dies or electronic systems fail.

Real-time monitoring is available via your smartphone, though this requires an additional Wi-Fi hub. You receive alerts about lock status from anywhere. The lock also supports rekeying, meaning you can replace the key cylinder without changing the entire lock mechanism. This feature simplifies security updates when tenants change or keys are lost. The combination of digital convenience and mechanical backup provides a practical solution for everyday home security.

Check compatibility and hub needs

Before you finalize your purchase, verify that your door is compatible with this right-handed fingerprint edition. The unit measures 3.15 inches wide, so ensure your door stile can accommodate these dimensions. You will need to check if your existing deadbolt hole aligns with the new mechanism. Although installation uses common tools, confirming your door’s thickness and backset is essential for a secure fit. This lock pairs well with video doorbells for a complete entry system. However, note that real-time alerts require an additional Wi-Fi hub. Without it, you only receive offline access codes. Maintenance involves keeping the sensor clean and checking battery levels. The mechanical parts are robust, but the electronics depend on power. Ensure your home network supports the required hub connectivity. This setup suits those who want biometric convenience alongside traditional key backups. It fits well in homes where quick entry is a priority. Consider how this integrates with your current smart home devices before buying.

Check before you buy

• Verify your door is right-handed for this specific edition.
• Confirm your door thickness matches the lock's requirements.
• Check if you have a Wi-Fi hub for alerts.
• Ensure your door backset fits the deadbolt mechanism.
