How to Pair Your Nuki Fob with a Smart Lock: A Complete Setup Guide

The Nuki Fob is a compact and convenient remote control that lets you lock or unlock your door without pulling out your phone. Whether you are arriving home with full hands or want to give a family member a simple keyless solution, the Fob offers one‑touch operation. Pairing it with your Nuki Smart Lock is a straightforward process that takes just a few minutes.

In this guide, we will walk you through the entire pairing procedure, from preparation to final testing. You will also learn how to pair the Fob with multiple locks, use it alongside accessories like the keypad-2-nfc-208682">Keypad 2 NFC, and resolve common issues. By the end, you will have a reliable wireless fob that works seamlessly with your smart lock system.

What You Need Before Pairing

Before you begin, ensure that your Nuki Smart Lock is installed and fully functional. The Fob is compatible with all current‑generation Nuki locks, including the Smart Lock Pro (5th Gen), Smart Lock Ultra, and Smart Lock Go. You will also need the Nuki app installed on your smartphone (iOS or Android) and a stable Bluetooth connection to your lock.

Make sure the Fob has a fresh CR2477 battery. The Fob does not require charging and will last approximately one year under normal use. Keep the Fob within a few meters of the lock during the pairing process, and confirm that your smartphone is connected to the lock via Bluetooth in the app. If you have multiple Nuki locks at your property, decide which one you want to pair first.

• Tip: If you are pairing the Fob for the first time, remove the plastic tab from the battery compartment to activate it.

Step‑by‑Step Pairing Process

Open the Nuki app on your smartphone and navigate to the settings menu of the lock you want to pair. Scroll down to the “Keypad & Fob” section and select “Add Fob”. The app will prompt you to press and hold the button on the Fob for three seconds. A short vibration confirms that the Fob is in pairing mode. The lock’s LED ring will flash blue, indicating it is searching for the Fob.

Once the Fob is detected, the app will display a confirmation message. Give the Fob a custom name (e.g., “John’s Fob” or “Blue Fob”) to help distinguish it if you pair multiple units. Tap “Save” and the Fob will be added to your lock’s access list. You can now test the Fob by pressing its button once to lock or unlock the door. The lock should respond immediately with a gentle motor sound and the LED ring will turn green.

• Note: If pairing fails, restart the lock by removing its battery cover for 10 seconds, then try again.

Pairing the Fob with Multiple Locks

If you have more than one Nuki Smart Lock — for example, a Smart Lock Ultra on your front door and a Smart Lock Pro (5th Gen) on a side entrance — you can pair the same Fob with up to three locks. To do so, repeat the pairing process from the app for each additional lock. The Fob will automatically control the lock that is in range, pressing the button once to toggle the nearest paired lock.

This feature is especially useful in apartment buildings or homes with multiple entry points. You do not need to buy separate Fobs for each door. Remember that the Fob communicates only via Bluetooth, so it must be within approximately 10 meters of the lock to work. For extended range, consider pairing the Fob with a Nuki Smart Lock Pro (5th Gen), which offers longer Bluetooth reach.

• Tip: Label each Fob with a sticker or colour code if you use several for different family members.

Using the Fob with Nuki Accessories

The Fob works independently, but its convenience multiplies when combined with other Nuki hardware. For instance, you can mount a Keypad 2 NFC near your door as a backup entry method for guests who do not have a Fob. The Keypad 2 NFC also supports tap‑to‑open with supported phones and cards, making a great complementary device.

Another useful accessory is the Door Sensor, which notifies you when your door is opened or closed. Pairing a Fob with the Door Sensor ensures you never accidentally leave your door unlocked after arriving home. If you have a Nuki Power Pack installed, the Fob’s battery life becomes less critical because the lock itself stays powered even during a power outage. The Fob remains your reliable, pocket‑sized remote for everyday use.

• Pro tip: Use the Nuki Fob together with the Smart Lock Pro (5th Gen) and Keypad 2 NFC for a fully connected entry system.

Troubleshooting Common Pairing Issues

If the lock does not react when you press the Fob button, first check whether the Fob’s battery is installed correctly. Replace the CR2477 battery if needed. Next, ensure that the lock’s Bluetooth is enabled and that you are within range. If the lock was recently installed, verify that the lock’s firmware is up‑to‑date via the Nuki app.

Pairing failures often occur when the lock is already paired to the maximum number of Fobs. The Smart Lock Pro (5th Gen) and Smart Lock Ultra can handle up to 10 Fobs each. If you have reached that limit, remove an unused Fob from the app first. Also make sure no other Bluetooth devices are interfering. Restarting the lock by disconnecting the battery for 30 seconds usually resolves most issues.

• Reset the Fob: Remove the battery, wait 10 seconds, reinstall it, and the Fob will automatically re‑enter pairing mode.

Pairing a Nuki Fob with your smart lock takes only a minute, yet it adds a whole new level of convenience to your daily routine. Whether you pair it with a single lock or multiple, the Fob will let everyone in your household enjoy keyless entry without needing a smartphone. Ready to simplify your access?
