Sifely Keyless Keypad Fingerprint Biometric Smart Lock Review

Welcome back to AllSmartLocks.com, where we provide detailed breakdowns of the latest smart lock innovations to help you make informed choices. We’ve had the Sifely Keyless Keypad Fingerprint Biometric Smart Lock installed on our test door, subjecting it to extensive use. We selected this model to assess whether a smart lock with six entry methods—fingerprint, passcode, key fob, card, app control, and physical key—could offer consistent performance. We incorporated the optional WiFi Gateway from the beginning to evaluate remote capabilities. This evaluation involved rental simulations and exposure to various conditions. The outcome? The Sifely Keyless Keypad Fingerprint Biometric Smart Lock stands out as a versatile lock with quick access and guest management. However, environmental concerns and occasional recognition issues impact reliability. Let’s examine the details, step by step.

Unboxing and First Impressions of Sifely Keyless Keypad Fingerprint Biometric Smart Lock

The packaging arrived securely. Everything inside was well-organized, with protective foam to prevent damage during transit. You get the black exterior assembly with the integrated fingerprint sensor and touchscreen keypad, the interior handle mechanism, two key fobs for contactless entry, two physical keys tucked under a protective cover, an adjustable latch for different door backsets, a complete hardware pack including screws and mounting plates, and a detailed template with a QR code linking to a setup guide video.

Impressions were positive right from the start. The stainless steel build in black feels sturdy and substantial at 4 pounds, giving a sense of durability without being overly heavy. Furthermore, the black finish effectively resists smudges and fingerprints, maintaining a clean look over time. It appears modern and sleek without unnecessary bulk, fitting well on contemporary doors. The fingerprint sensor responded quickly during initial handling, and the keypad illuminates promptly on approach, making it easy to see in dim lighting. Some users report that the components feel high-quality and intuitive to assemble, aligning with our experience where everything snapped together smoothly. However, we noted that minor plastic parts, like covers, could potentially loosen with rough handling, though this didn’t affect functionality in our setup.

Installation Process of Sifely Keyless Keypad Fingerprint Biometric Smart Lock

Replacing a standard lock with this model is straightforward, typically requiring just a Phillips screwdriver and no drilling, which makes it accessible even for those with limited DIY experience. It suits doors with thicknesses from 1 5/16″ to 2″ (33mm-50mm), bore holes of 2 1/8″ (54mm), and backsets of 2 3/8″ or 2 3/4″ (60mm or 70mm). The reversible handle accommodates left- or right-handed orientations, adding to its flexibility. We rate the installation highly, as it took minimal time and effort. It compares favorably to similar models, though users with non-standard doors may need extra adjustments, such as shimming for perfect alignment. In our testing, the process felt intuitive, and some users report completing it quickly, emphasizing how user-friendly the instructions are.

Step 1: Door Prep and Template for Sifely Keyless Keypad Fingerprint Biometric Smart Lock

• Align the included template to verify measurements and mark positions if needed, ensuring everything lines up precisely to avoid misalignment issues later.
• Remove the existing lock and ensure the bore hole and backset match; note potential interference with screen or storm doors, which could require additional spacing or modifications.
• Check the latch direction and adjust as necessary for proper fit, testing the door swing to confirm smooth operation before proceeding.

We found this step crucial for a hassle-free install, and some users mention that taking time here prevents common pitfalls like crooked mounting.

Step 2: Assembly and Cable for Sifely Keyless Keypad Fingerprint Biometric Smart Lock

• Install the exterior unit with the keypad and fingerprint handle, threading the cable through the door carefully to prevent any kinks or damage.
• Attach the interior back plate and secure with screws; connect the cable carefully to avoid pinching, which could lead to connectivity problems.
• Verify alignment to ensure smooth handle operation, turning it a few times to check for any binding or resistance.

During our assembly, the parts fit together seamlessly, and some users report that the reversible design made it adaptable to different door configurations without extra tools.

Step 3: Power-Up and Bluetooth Pairing for Sifely Keyless Keypad Fingerprint Biometric Smart Lock

• Insert four AA batteries (not included) and power on; pair with the Sifely app via Bluetooth for initial configuration, which connects reliably in close proximity.
• Optional: Add the WiFi Gateway for remote features during this step, enhancing the lock’s capabilities for distant management.
• Test basic functions like locking and unlocking to confirm successful setup, listening for audible feedback to ensure everything is operational.

We appreciated the quick pairing process, and some users note that the app guides you through it effectively, making it straightforward even for tech novices.
