If you are not sure, send us a picture of your door lock to firstname.lastname@example.org.
Does the cylinder have one of the following shapes on the inside of the door? (1/7)
The Nuki Smart Lock is mounted on the cylinder on the inside of your door. It is important that the cylinder has the shape of the Euro Profile cylinder or the Swiss roundcylinder.
The orientation of the keyhole doesn't matter, it is just about the outer shape. More information on cylinders and the installation requirements for Nuki Smart Lock can be found here.
Can you lock the door from the outside, even if there is a key inserted on the inside? (2/7)
We recommend mounting the Nuki Smart Lock only on door locks that feature the so-called emergency and hazard function (a.k.a. BSZ or priority function). This function allows you to open the door with your physical key in an emergency when a Nuki Smart Lock is mounted on the inside of the door. Please note that the key on the inside of the door should also turn when you unlock the door from the outside. More information about the emergency function.
Do you have an iPhone (4S or higher) or a smartphone with Android operating system (Android 4.4 or higher)? (3/7)
To be able to set up a Smart Lock you need the Nuki app. The Nuki app is available for Android (4.4 or higher) and iOS devices (iPhone 4S or higher). You can download it from the app stores (for free).
