Nuki Keypad 2 vs Smart Lock Go: Which Compact Access Solution Fits Your Door?

When it comes to upgrading your door with smart access, two compact solutions from Nuki often stand out: the Nuki keypad-2-208683">Keypad 2 and the Nuki Smart Lock Go. Both are designed to make keyless entry more convenient, but they serve very different purposes. While the Keypad 2 is an accessory that adds a code-entry option to your existing smart lock setup, the Smart Lock Go is a standalone smart lock that fits directly on your door. Choosing between them depends on your current setup, your door type, and how you want to control access.

In this comparison, we'll break down the key differences between the Nuki Keypad 2 and the Smart Lock Go, covering installation, functionality, and ideal use cases. By the end, you'll know exactly which compact access solution deserves a spot on your door.

Nuki Keypad 2: A Convenient Add-On for Code Entry

The Nuki Keypad 2 is a sleek, weatherproof keypad that attaches to the outside of your door. It's not a lock itself; instead, it works in tandem with a compatible Nuki smart lock, such as the Smart Lock Pro (5th Gen) or Smart Lock Ultra. With the Keypad 2, you can enter a numeric code to unlock your door, eliminating the need to fumble for keys or use your smartphone every time you arrive home.

The Keypad 2 is particularly useful for households with multiple users, like family members or frequent guests. You can assign unique codes to different people and easily revoke them when needed, all from the Nuki app. It's also a great solution for those who prefer a physical code entry over app-based access, especially when your phone battery is low or you're carrying groceries.

• Requires a compatible Nuki smart lock to function
• Weatherproof design for outdoor use
• Supports multiple user codes and temporary access

Smart Lock Go: A Standalone Smart Lock for Compact Doors

The Nuki Smart Lock Go is a complete smart lock solution designed for interior and exterior doors that don't have a standard euro cylinder. It's a compact, battery-powered lock that replaces your existing thumb turn or latch, making it ideal for apartment doors, office doors, or even internal rooms. Unlike the Keypad 2, the Smart Lock Go works independently—no need for an additional smart lock.

The Smart Lock Go connects to your smartphone via Bluetooth and supports Apple HomeKey, so you can unlock it with your iPhone or Apple Watch. It also integrates with Matter, allowing seamless control through smart home platforms like Apple Home, Amazon Alexa, and Google Home. For those who want a simple, all-in-one smart lock for a non-standard door, the Smart Lock Go is a compelling choice.

• Works as a standalone lock, no extra hardware needed
• Supports Apple HomeKey and Matter
• Compact design fits doors with thumb turn or latch

Key Differences at a Glance

The most significant difference is that the Keypad 2 is an accessory, while the Smart Lock Go is a full lock. This means the Keypad 2 requires a compatible Nuki smart lock to function, whereas the Smart Lock Go is self-contained. If you already own a Nuki smart lock, adding a Keypad 2 is a cost-effective way to enable code entry. On the other hand, if you're starting from scratch and have a door that doesn't accommodate a standard euro cylinder, the Smart Lock Go is your best bet.

Another difference is in the user experience. The Keypad 2 offers a familiar PIN code entry, which many people find intuitive. The Smart Lock Go, however, offers the convenience of Apple HomeKey and smartphone control, but it lacks a physical keypad—so you'll need your phone or an Apple Watch to unlock. If you prefer a backup code option, you might consider pairing the Smart Lock Go with a separate keypad, though that would require a compatible lock.

• Keypad 2: add-on for existing smart locks, code entry
• Smart Lock Go: standalone lock, phone-based access
• Consider your door type and current setup

Which One Should You Choose?

The decision ultimately comes down to your current situation. If you already have a Nuki smart lock installed and want to add a convenient code entry option for family or guests, the Nuki Keypad 2 is the perfect companion. It's an affordable upgrade that enhances your existing setup without replacing anything.

If you don't have a smart lock yet and your door has a thumb turn or latch (common in many apartments), the Nuki Smart Lock Go offers a complete smart access solution in one compact device. It's especially appealing if you're an Apple user, thanks to HomeKey support, and if you want a lock that works with Matter for broader smart home compatibility.

• For existing Nuki users: Keypad 2 is a smart addition
• For first-time smart lock buyers: Smart Lock Go is a great standalone option
• Consider your door type and whether you want a keypad or phone-based access

Both the Nuki Keypad 2 and the Smart Lock Go are excellent compact access solutions, but they cater to different needs. If you're looking to upgrade an existing Nuki smart lock with keyless code entry, the Keypad 2 is a practical and affordable choice. If you're starting fresh and need a standalone lock for a non-standard door, the Smart Lock Go offers modern features like HomeKey and Matter. Evaluate your door type, existing equipment, and preferred access method to make the right call.
