The door first. Then the model.
Does Nuki suit your home?
Choosing the right smart lock starts with a door check. We assess the cylinder, fittings, available space and locking mechanism together.
- Existing cylinder: Pro for suitable key-operated cylinders; Go also supports certain knob cylinders, depending on the configuration.
- Cylinder replacement: Ultra uses the supplied Universal Cylinder.
- Door mechanism: Smooth locking and sufficient space on the inside.
- Backup access: Check mechanical access and plan charging in advance.
The Nuki app
One way in.
For Android and iOS.
Operate your lock, manage permissions and adjust settings to your routine. The examples show the German Nuki app on Android.
For your smartphone
Nuki requires Bluetooth 4.0 or later and supports the current and two previous iOS and Android versions. Current download links are available from the manufacturer.
Set up convenience features properly

A smart home that fits your life
Your door becomes part
of your connected home.
Matter over Thread lets suitable Nuki Smart Locks connect to supported systems. We establish which hub you have and which routines you would like.
Apple HomeGoogle HomeAmazon AlexaSamsung SmartThings
Nearby
Your smartphone controls Nuki via Bluetooth. Convenient for direct operation at the door.
In your smart home
Matter connects compatible devices. A suitable Matter hub and a Thread Border Router are needed, often combined in one device.
Away from home
Remote access requires suitable setup and internet connectivity. On Nuki Go, Nuki Remote Access is activated separately.
We plan lighting, heating and occupancy routines around your platform's capabilities. Features and voice control depend on the system.

The right controls.
For everyday life.
Family, guests, office or shared entrance: accessories extend access where you need it.
Keypad, Keypad 2 & NFC
Access by code, with fingerprint access on Keypad 2 and NFC on Keypad 2 NFC. We check the compatible smartphone and wallet features for your specific setup.
Opener & Bridge
For suitable intercoms: Opener operates the electric door release. A Bridge enables Nuki remote access. The intercom manufacturer and model determine compatibility.
Door Sensor & other accessories
Door Sensor adds information about whether the door is open or closed. Fob and Power Pack are further options for suitable models. We select accessories around your routine.
Flat door and shared building entrance
Apartment buildings may need different solutions: a Smart Lock on the flat door, an Opener on a compatible intercom or a centrally planned building solution. We involve property management and clarify existing equipment and responsibilities early.

Frequently asked questions
Good to know.
Before your first unlock.
Does your door need a closer look?
Ask your question →Does a Nuki Smart Lock fit every door?
That depends on the cylinder, fittings and door mechanism. Go and Pro can be retrofitted inside a suitable door; Ultra involves replacing the cylinder. We also check clearance, smooth operation and mechanical access from outside.
Can I use Nuki with Android and iPhone?
Yes, the Nuki app is available for Android and iOS. Nuki specifies Bluetooth 4.0 or later and supports the current and two previous operating system versions. Without Google Play Services, Android lacks features including Auto Unlock and certain notifications.
Do I need Wi-Fi, internet or a Bridge?
Nearby operation uses Bluetooth. Access away from home requires a configured remote access solution and internet. Pro (5th generation) and Ultra include Wi-Fi and Remote Access. Nuki Remote Access can be activated separately on Go. Opener can be controlled remotely through a Bridge.
Does Nuki work with Apple Home, Google Home or Alexa?
Suitable Nuki Smart Locks support Matter over Thread, including integration with Apple Home, Google Home, Amazon Alexa and Samsung SmartThings. A compatible Matter hub and Thread Border Router are required. Available features depend on the platform, devices and software.
Can I open the door without a smartphone?
Depending on your setup, you can use a key, Fob or Keypad. Keypad supports codes, Keypad 2 adds fingerprint access and Keypad 2 NFC adds NFC. We check smartphone and wallet features for the particular combination.
What happens if the battery runs out or the internet fails?
Remote access stops without internet; local Bluetooth operation requires a charged Smart Lock and a suitable phone. The motor cannot operate with an empty lock battery. Charging plans and verified mechanical access from outside therefore form part of the setup.
Can I give family or guests temporary access?
The Nuki app lets you manage individual permissions and set time limits. We discuss who may administer access, how permissions are revoked and which controls suit family or guests.
What does Nuki cost including installation in Berlin?
The total depends on the Smart Lock, accessories, any cylinder replacement and setup. After assessing your door, we provide a quotation covering equipment and agreed services. You can request a free initial consultation directly from Kondul.
