During calibration, your Smart Lock will know your lock the first time you set it up and save the minimum and maximum lock positions. These two stops define the locking rotation.
After the calibration, you can check the lock status via your Nuki app or Web account.
What causes the calibration of the Smart Lock to be lost?
The status of the Smart Lock can be lost due to external influences. For example, if the door is stiff or needs to be adjusted. Re-calibration may also be required after manual locking with the physical key. This happens when the inner and outer keys do not turn synchronously.
We recommend using a cylinder with emergency function. The emergency function means you can unlock your door from the outside even if a key is inserted inside. You can do this in any position of the key—the inner and outer keys turn synchronously. With this, your Smart Lock always knows if your door is locked or unlocked.
How to correct the lock state?
Calibration within Bluetooth range of the Smart Lock
The best and safest solution is re-calibrating your Smart Lock within Bluetooth range. When you are on-site, you can ensure that the calibration was successful and that the door stays closed.
To re-calibrate your Smart Lock, tap on the desired Smart Lock in the Nuki app and enter the lock settings. Then go to "Features & Configuration". Here, you can find the option "Calibrate Smart Lock" to initiate a new calibration.
Lock your door using the Nuki app or Nuki Web
If you are not on site, you can lock your door via app or Web to correct the state of your Smart Lock. When locking, your Smart Lock turns the key until it reaches the endpoint. The state is thus known again and the Smart Lock is ready for use.
In rare cases, the Smart Lock may turn the key in the opposite direction due to a loss of position. The door is, therefore, opened and not locked.
We therefore recommend only using locking to correct the state if a person on site can check that the door is closed and locked.
