Does the cylinder have one of the following shapes on the inside of the door? (1/7)
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. 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)
If there is a key inserted on the inside of your door and you can still lock from the outside, your lock is equipped with the emergency function (also called external key override function).
You need this function to be able to lock the door with your physical key from the outside, when Nuki Smart Lock is installed inside. To ensure that the Smart Lock is working correctly, your key should rotate on the inside when you lock from the outside.
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).
