Frequently asked questions

• How secure is Nuki?

  The Smart Lock communication is end-to-end encrypted. Our security standards are comparable with those of the online banking sector. We have been audited and marked out by independent security experts and institutions.

• Can I carry on unlocking / locking the door with my key?

  If your lock cylinder has an emergency function, you can carry on locking with your old key. If you can still turn the key from the outside even if a key is in the lock on the inside, the lock has an emergency function. You can use the Nuki Smart Lock on locks without an emergency function (or priority function). However, we recommend to use the Smart Lock on locks with an emergency function only. You can have the emergency function retro-fitted to your existing door lock. For this, contact your locksmith.

• What happens if the Smart Lock’s batteries go flat?

  The Nuki Smart Lock works with four standard AA batteries. As soon as the battery charge level falls below 20%, the Nuki app notifies you and you have sufficient time to change the batteries. Also you can use your key to lock/unlock if your door lock has an emergency function. Average battery life is around 6 months. Your Smart Lock’s power consumption depends on the frequency of locking/unlocking actions and the ease of actuation of the lock. You can find more information about the batteries here.

• How can I unlock the door if I’ve forgotten my smartphone or the battery is flat?

  There are many potential ways to actuate your Nuki Smart Lock if your smartphone isn’t available. Nuki offers different add-ons, such as the Nuki Fob or the Nuki Keypad which enable to lock/unlock the door without a key or smartphone. You can also log into your Nuki Web account via any device with Internet access and open the door from there. If necessary you can also unlock your door with your normal key if your door lock has an emergency function.
