Frequently asked questions

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

  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 secure is Nuki?

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

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

  There are many potential ways to actuate your Nuki Smart Lock if your smartphone isn’t available. One alternative is the compact Nuki Bluetooth fob with which you can unlock / lock 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.

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

  If your lock cylinder has an emergency function you can carry on operating the lock with your old key. You can verify this function by checking that you can still operate the lock with a key from the outside even if a key is engaged on the inside. The existence of an emergency function is verified if one key is engaged and the other can nevertheless be turned. You can use Nuki in the absence of an emergency function (or priority function), but we advise against it in principle. You can have the emergency function retro-fitted to your existing door lock. For this, contact your favoured locksmith.
