Nuki Smart Lock Pro (4th Gen)
Best OverallPros
- Matter support for Apple Home, Google, Alexa
- Fastest motor in the Nuki range
- Reliable auto-unlock via geofencing
Cons
- Requires Bridge for remote access (included)
- Higher price than 3rd Gen
The Nuki Smart Lock Pro (4th Gen) is the flagship model for 2026. It features a new motor that cycles the deadbolt in under half a second, making it the quickest Nuki lock to date. The built-in Matter controller allows direct integration with Apple Home, Google Home, and Amazon Alexa without extra hubs, though the included Nuki Bridge is still needed for full remote access via Wi-Fi.
Owner reviews consistently praise the improved auto-unlock algorithm, which uses a combination of geofencing and BLE signal strength to unlock the door as you approach. The battery life remains strong at around 12 months with standard use, and the lock retains the same retrofit design that fits most European standard deadbolts.
Nuki Smart Lock (3rd Gen)
Best Value / BudgetPros
- Lower price than Pro model
- Thread support for Apple Home
- Same reliable retrofit design
Cons
- Slower motor than 4th Gen
- No Matter support
The 3rd Gen Nuki Smart Lock remains a strong contender for those who want keyless entry without the premium price tag. It uses BLE for local control and Thread for integration with Apple Home hubs, though it lacks the Matter compatibility of the newer Pro model. The motor is slightly slower at around one second, but this is still fast enough for daily use.
Owner reviews note that the auto-unlock feature works well, though it can be slightly less reliable than the 4th Gen Pro due to the older sensor suite. The lock is compatible with the same Nuki Keypad, Fob, and Opener accessories, making it easy to expand later. Battery life is similar to the Pro at about 12 months.
Nuki Smart Lock Ultra
Smallest Form FactorPros
- Smallest and most discreet design
- Fits on doors with limited space
- Thread support for Apple Home
Cons
- Shorter battery life
- No Wi-Fi or Matter
The Nuki Smart Lock Ultra is designed for doors where space is tight, such as narrow frames or doors with existing hardware. It uses two CR123A lithium batteries instead of four AAs, which allows for a much smaller housing. The trade-off is a shorter battery life of around six months, and the motor is slightly slower at 1.2 seconds.
Owner feedback highlights the Ultra's discreet appearance, as it protrudes less from the door than the standard models. It supports Thread for Apple Home, but lacks Wi-Fi and Matter, so remote access requires a separate Nuki Bridge. It is a good choice for secondary doors or apartments where space is at a premium.
Nuki Keypad 2.0 + Smart Lock Bundle
Best for Touch EntryPros
- Physical keypad for guests without phones
- Backlit keys for night use
- Weather-resistant design
Cons
- Added cost for keypad
- Requires Bridge for remote access
The Nuki Keypad 2.0 bundle pairs a 3rd Gen Smart Lock with the official keypad, allowing you to unlock the door with a PIN code. This is ideal for families, guests, or service providers who do not have the Nuki app. The keypad mounts on the door frame or wall and communicates with the lock via BLE, with a range of about 10 meters.
Owner reviews appreciate the keypad's backlit keys and weather-resistant build, which holds up well to rain and sun. The lock itself is the standard 3rd Gen model, so you get the same reliable performance and battery life. The bundle saves a small amount compared to buying the lock and keypad separately.
Nuki Opener + Smart Lock
Best for Garage/Flat DoorsPros
- Controls both deadbolt and flat/garage door
- Opener module is wired for constant power
- Works with most intercom systems
Cons
- Complex installation for opener
- Requires Bridge for full functionality
The Nuki Opener is an add-on module that works with the Smart Lock to control flat doors, garage doors, or intercom systems. It connects to the lock via BLE and can be triggered by the same app, keypad, or fob. The Opener itself is wired via USB-C, so it does not need battery changes, but it does require a nearby power outlet.
Owner reviews note that the Opener is a niche product, best suited for those who need to automate a second door alongside their main entrance. Installation can be more involved than the standard lock, as it may require wiring into an existing intercom. It is a solid choice for flats with buzzer systems or garages with compatible openers.
What to Check Before Buying a Nuki Keyless Door Lock
Door compatibility: Nuki locks are designed for European standard deadbolts with a square spindle. Measure your door thickness and ensure the lock fits between the door and the frame. The Ultra model is best for narrow doors.
Connectivity needs: If you want remote access via Wi-Fi, you need the Nuki Bridge or a 4th Gen Pro with Matter. For local control only, BLE is sufficient. Thread supports Apple Home without a Bridge.
Battery life: Standard models use 4x AA batteries and last about 12 months. The Ultra uses CR123A cells and lasts around 6 months. Consider how often you want to change batteries.
Accessories: The Keypad, Fob, and Opener expand functionality. Decide if you need physical entry methods for guests or second doors before buying.
Common Mistakes to Avoid
Ignoring door alignment: Nuki locks require a well-aligned deadbolt. A misaligned door can cause the motor to struggle or fail. Check your door alignment before purchasing.
Skipping the Bridge: Without a Bridge or Matter hub, you cannot control the lock remotely. Many users buy a 3rd Gen lock and later realize they need the Bridge for remote access.
Overlooking firmware updates: Nuki regularly releases firmware updates that improve performance and security. Ensure your lock is updated via the app after installation.
