Frequently asked questions

  • How secure is Nuki?

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

    If your lock cylinder has an emergency function, you can still use your old key. If you can still lock your door from the outside when there is already a key in the lock on the inside, then your lock has an emergency function. You can use the Nuki Smart Lock on locks without an emergency function (or priority function). However, we recommend only using the Smart Lock on those with an emergency function. You can have your existing door lock retrofitted with an emergency function. 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, giving you sufficient time to change the batteries. You can also use your key to lock/unlock your door if the lock has an emergency function. The average battery life is around 6 months. Your Smart Lock’s power consumption will depend on the frequency of locking/unlocking actions and how smoothly they can be carried out. 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 a variety of add-ons, such as the Nuki Fob or Nuki Keypad, which enable you to lock/unlock the door without a key or smartphone. You can also log into your Nuki Web account using 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 lock has an emergency function.
