Who it fits

Key specs explained for Nuki

Access Method: Keypad, Fingerprint, App Control

You can unlock the door using a numeric code, your fingerprint, or the mobile application. This variety means you are not reliant on a single method. If your phone battery dies, the keypad still works. If you forget your code, your fingerprint is a reliable backup. This flexibility suits households with diverse access needs.

Smart Home Compatibility: Alexa, Google Assistant

The lock integrates with major voice platforms to allow hands-free control. You can ask your assistant to lock the door or check its status. This compatibility ensures the device fits into existing smart home ecosystems without requiring a separate hub. It supports a unified control experience for your connected devices.

Special Features: Auto Lock

The mechanism automatically engages the deadbolt after you close the door. This feature removes the need to manually turn the lock or confirm it via the app. It provides consistent security by ensuring the door is secured every time. This is useful for busy residents who want to eliminate the risk of forgetting to lock up.

Color: Silver and Black

The device combines metallic silver accents with black housing for a modern aesthetic. This color scheme is designed to blend with various door styles and hardware finishes. It offers a neutral look that does not clash with exterior paint or trim. The finish is chosen to maintain a clean appearance on your entryway.

Design and Build Overview

According to the listing, the Nuki Smart Lock with Keypad 2 NFC features a silver and black finish. The internal lock unit measures 2.24 inches in width, 2.28 inches in height, and 2.24 inches in length. It weighs 12 ounces. These compact dimensions allow the device to mount directly over your existing deadbolt without requiring major modifications. The small footprint ensures it does not protrude excessively, maintaining a clean look on most residential doors.

The wireless keypad is designed for exterior use with an IP54 weather-resistant rating. This specification means it can withstand rain and dust, making it suitable for outdoor mounting. You can attach it using adhesive strips or screws. The listing notes that no drilling or wiring is required for the keypad, which simplifies the installation process significantly. This flexibility allows you to position the keypad at a comfortable height without complex construction work.

The system relies on Bluetooth, Wi-Fi, and Matter over Thread for connectivity. These options ensure reliable communication between the lock, keypad, and your smartphone. The bank-level encryption and end-to-end protected communication are built into the hardware. Local data storage further enhances security by keeping sensitive information on the device itself. This design choice prioritizes privacy while maintaining easy access through the free Nuki app.

Setup and Everyday Use Guide

The listing states you can install this system over your existing deadbolt in under fifteen minutes. You do not need to drill holes, run wiring, or replace the entire lock mechanism. The internal smart lock unit mounts directly to the interior side. Outside, you attach the wireless keypad using adhesive strips or screws. This design allows for a quick retrofit without major construction work.

For daily operation, you have multiple ways to enter your home. You can use a numeric code on the keypad, place your finger on the fingerprint sensor, or use your smartphone via the app. The system also supports NFC taps and auto-unlock features when you approach the door. You can create up to two hundred entry codes and store up to twenty fingerprints. This allows you to manage access for family members or guests without handing out physical keys. You can adjust permissions and view activity logs through the free Nuki app.

Connectivity relies on Bluetooth, Wi-Fi, and Matter over Thread. This ensures the lock stays connected to your network for remote commands. It also integrates with Apple Home, Alexa, Google Home, and SmartThings. You can automate the lock to engage automatically after you close the door. The keypad carries an IP54 rating, meaning it resists dust and water splashes for outdoor use. The lock itself uses bank-level encryption to protect your data locally. This setup provides a reliable, keyless entry method that adapts to your routine.

Before You Buy This Lock

You should verify your door type before purchasing. This unit fits over existing deadbolts, but you must confirm the strike plate aligns with the new mechanism. Check your smartphone compatibility carefully. The listing notes support for Apple Home Key and Samsung Digital Home Key, but you need a compatible device to use these features. Ensure your Wi-Fi network is stable, as the lock uses Wi-Fi and Bluetooth for remote access. You will also need to set up the free Nuki app to manage up to two hundred entry codes and thirty-five tap-to-unlock keys. Regular upkeep involves recharging the internal battery. Keep the keypad clean to maintain its IP54 weather resistance. This system complements video doorbells by adding secure, keyless entry. It integrates with Alexa and Google Home for voice control. Consider how it fits into your current smart home setup. If you already use Apple or Samsung ecosystems, this lock may integrate smoothly. Otherwise, standard app control remains available.

Check before you buy

• Confirm your door has a compatible existing deadbolt.
• Check if your phone supports Apple Home Key.
• Verify Wi-Fi strength at the entryway.
• Ensure space for the internal lock unit.
