How to Install Nuki Smart Lock Go: A Quick Step-by-Step Guide

The Nuki Smart Lock Go is the perfect choice for renters, apartment dwellers, or anyone with a smaller door who wants reliable smart access without the bulk. Its compact design fits standard European doors, and the installation is surprisingly straightforward — even if you’ve never installed a smart lock before. In this guide, we’ll walk you through every step of the installation, from unboxing to final testing, so you can enjoy keyless entry with minimal hassle.

Before you start, make sure you have the Nuki Smart Lock Go, the included mounting plate, adhesive pads (if needed), and a smartphone with the Nuki App installed. The entire process typically takes 20–30 minutes and requires no special tools — just a screwdriver and a bit of patience. Let’s get started.

What You’ll Need Before Installing the Nuki Smart Lock Go

First, confirm that your door meets the compatibility requirements. The Smart Lock Go works with most standard European doors that have a round or oval cylinder, a diameter between 22–30 mm, and a cylinder length of 60–80 mm. If your door has an unusual cylinder, measure it carefully or check the Nuki compatibility checker on the product page.

In the box you’ll find the Smart Lock Go unit, a mounting plate, adhesive strips (for temporary installation if you’re renting), and a quick-start manual. You’ll also need a Phillips-head screwdriver to attach the mounting plate. For the best experience, we recommend pairing the lock with a keypad like the Keypad 2 for keyless entry when you don’t have your phone — but that’s optional and can be added later.

• Double-check door cylinder measurements: length 60–80 mm, diameter 22–30 mm.
• Download the Nuki App from the App Store or Google Play before you start.
• Ensure your smartphone has Bluetooth 4.0 or newer (most modern phones do).

Step 1: Prepare Your Door Cylinder

Begin by removing any existing keys from the inside of the door. If you have a double-cylinder lock, you may need to loosen the cylinder screw (usually on the edge of the door) to pull out the cylinder, but this is rarely required for the Smart Lock Go. The lock mounts directly over the cylinder on the inside of the door.

Clean the area around the cylinder with a dry cloth to ensure the adhesive (if you’re using it) or the mounting plate sits flush. This is especially important if your door is painted or has dust buildup. A clean surface prevents the lock from wobbling after installation.

Step 2: Attach the Mounting Plate

Take the metal mounting plate and align it so that the large hole sits directly over the cylinder. The plate should be centered. If your door has a rosette (the decorative ring around the cylinder), you may need to remove it first using a flathead screwdriver. Most rosettes snap off easily.

Secure the mounting plate using the two screws provided. Tighten them firmly but not excessively — you don’t want to strip the threads. For rental apartments where you can’t drill, the included adhesive pads work well. Peel off the backing and press the plate firmly onto the door for 30 seconds. The Smart Lock Go’s low weight makes adhesion reliable.

• Tip: Use the adhesive pads if you plan to move out soon — no permanent damage.
• Make sure the mounting plate is perfectly level; a crooked plate affects lock rotation.

Step 3: Mount the Nuki Smart Lock Go

Now slide the Smart Lock Go onto the mounting plate. You’ll hear a click when it locks into place. The device is designed to fit snugly — if it feels loose, double-check that the plate is properly attached. Once mounted, the lock should rotate smoothly when you turn the thumb turn on the back of the unit.

The Smart Lock Go uses your existing key cylinder, so you don’t replace anything permanent. This is a huge advantage for renters: when you move out, simply detach the lock and reattach the original thumb turn — your landlord will never know.

Step 4: Power On and Pair with the Nuki App

Press the button on the side of the Smart Lock Go to power it on. The LED will flash. Open the Nuki App and tap “Add Device.” Follow the on-screen instructions to pair via Bluetooth. The app will ask you to test the lock’s rotation — turn the thumb turn manually as prompted to calibrate the motor.

During pairing, you’ll be asked to set a master PIN code for emergency access. Choose something memorable but secure. After a successful pairing, the app will show the lock status (locked/unlocked). You can now control the lock remotely via your smartphone or add other users.

• If pairing fails, ensure Bluetooth is enabled and your phone is within 2 meters of the lock.
• After pairing, install the Door Sensor to get real-time door open/close status — it’s a small add-on that boosts security.

Step 5: Test and Fine-Tune the Installation

With the app paired, test locking and unlocking several times. The Smart Lock Go should turn smoothly without excessive noise or resistance. If the lock struggles, you may need to adjust the mounting plate position slightly — loosen the screws, nudge the plate a millimeter, and retighten.

Also test manual operation: even if the battery dies (the Smart Lock Go runs on 4 AA batteries; consider a Power Pack for backup), you should still be able to turn the thumb turn manually from the inside. Always keep a physical key handy for the outside cylinder.

• Pro tip: Use the “Calibration” option in the Nuki App to optimize motor travel distance.
• Low battery? The app will notify you. Keep spare batteries or a Power Pack ready.

Optional: Add a Keypad for Keyless Entry

If you want to unlock your door without pulling out your phone, consider pairing the Smart Lock Go with the Keypad 2. The keypad attaches to the outside of your door (adhesive or screws) and connects wirelessly to the Smart Lock Go. You can assign unique PIN codes for family, guests, or service providers — and revoke them instantly from the app.

The Keypad 2 also features a backlit keypad for night use and IP65 weather resistance, making it a great companion for outdoor installation. Adding it takes just a few minutes and requires no extra wiring.

Installing the Nuki Smart Lock Go is a straightforward process that gives you smart access in under half an hour. Whether you’re a renter or a homeowner, the compact design and simple setup make it an excellent choice for upgrading your entry.
