The NUKI ULTRA smart lock is a modern solution for keyless access control. It is suitable for apartments, private houses, offices, and short-term rental properties, including Airbnb.
In all cases, you get full control over access — anytime and from anywhere in the world. You can unlock the door without a key, continue using mechanical keys, or integrate the lock into a master key system based on M&C cylinders.
The NUKI ULTRA motorized smart lock combines versatility, flexible settings, and advanced integration capabilities.
Smart Lock for Airbnb and Short-Term Rentals
The NUKI ULTRA electronic lock is a convenient solution for apartments rented on a short-term basis. It allows you to eliminate key handovers completely and automate guest access.
- automatic generation of PIN codes for guests
- access limited to the booking period
- remote door unlocking
- no need to meet guests in person
Versatility
The smart lock is available in versions compatible with both Euro profile cylinders and Scandinavian standard locks.
In the Euro version, the package includes a universal adjustable cylinder with a length ranging from 32+32 to 52+52 mm.
In addition to the standard configuration, we can supply the NUKI ULTRA with any M&C cylinder model, including non-standard sizes (up to 77+77 mm), as well as cylinders integrated into master key systems or “keyed alike” solutions.
A powerful motor with torque up to 2 Nm allows the smart lock to be used with multi-point locks.
One of the key advantages of the NUKI ULTRA is the built-in WiFi module. There is no need for additional hardware for remote access — simply connect the lock to your WiFi network and control it from anywhere.
Flexibility
Forget about keys. With the NUKI ULTRA, you can unlock your door using a smartphone, PIN code, fingerprint, or remotely via the app or a computer. If you do not use a smartphone, a dedicated keyfob is also available.
All these access methods offer maximum flexibility. You can grant access for a specific period, modify permissions, or revoke access at any time.
You can also install a wireless door sensor — the lock will automatically secure the door once it is closed.
At the same time, you can always unlock your door using a traditional mechanical key. NUKI is supplied with M&C cylinders certified according to the strict SKG*** security standard, ensuring protection against unauthorized key duplication.
Integration
NUKI can be integrated with several short-term rental platforms, including Airbnb. You can completely eliminate key management — guests will automatically receive access codes at the time you define. Their access will be limited strictly to the booking period.
In addition, NUKI integrates with Google Home, Amazon Alexa, Apple Home, and other smart home systems.
Additional Components
For basic operation, only the NUKI ULTRA smart lock is required. However, if you need extended functionality, a range of additional accessories is available.
Keypads
NUKI offers three types of wireless keypads, all suitable for outdoor use (operating temperatures from -20°C to +70°C).
For rental properties or offices, a standard keypad with PIN code access is an ideal solution (supports up to 200 codes).
For homes or apartments, you can choose a keypad with a fingerprint scanner, capable of storing up to 20 fingerprints.
The latest Keypad 2 NFC also allows unlocking the door using a smartphone with NFC support.
Keyfob
For users who prefer not to use smartphones or PIN codes, the NUKI Fob provides a simple solution — just press a button to unlock the door.
Door sensor
The wireless door sensor automatically locks the door once it is closed. You can also monitor the door status at any time via the NUKI app or web interface.
Frequently Asked Questions
Power Supply
The NUKI ULTRA uses rechargeable batteries. Battery life depends on usage frequency, required force, temperature, and other factors. Under ideal conditions, a full charge lasts for several months.
Installation. Can I install the lock myself?
Yes, DIY installation is possible. Please refer to the official installation guide and compatibility instructions.
What happens if the battery is completely discharged?
You can always unlock the door using a mechanical key. The NUKI ULTRA complements, rather than replaces, a traditional cylinder.
I have multiple rental apartments. Can I automate all of them?
This depends on the platform you use. For example, Airbnb allows you to assign a specific lock to each property and automate PIN code distribution for guests.
Are there any ongoing costs?
Using the NUKI ULTRA itself is free. However, some integrations (for example, Airbnb integration) may require a subscription fee.
I don’t have WiFi. Can I still use the lock?
Yes, the smart lock can be used without WiFi via Bluetooth, including all accessories (keypad, door sensor, remote). However, remote access will not be available without a WiFi connection.
