How secure is the Smart Lock?

How do I check if the Nuki Smart Lock fits my door
With our installation check, you can find out if your door lock is compatible with Nuki. You fasten or stick the Smart Lock to your existing cylinder on the inside of the door. This means both variants can be removed without leaving a trace, making them ideal for renters.
Since your Smart Lock is mounted on the door from the inside, no one on the outside can tell that you’re using an electronic door lock. Using a smart lock does not affect your insurance coverage. -
What do I do if don’t have a smartphone or my battery runs out?
If you’re out and about and don’t have your smartphone with you, there are other ways to unlock your door:- If your door lock has an emergency function, you can simply use your existing mechanical key.
- You can ask another person with an access permission to open the door for you. If you have a Nuki Smart Lock Pro or a Nuki Bridge for your Nuki Smart Lock, it will also work remotely.
- The Nuki Keypad or Nuki Fob offer you a perfect alternative for opening your front door quickly, easily and without a smartphone or physical key.

What happens if my batteries or the rechargeable battery pack in the Smart Lock run out?
When the battery level reaches approx. 20%, Nuki will inform you via the Nuki app and on the Smart Lock directly that the batteries or rechargeable battery pack are running low. This gives you enough time to insert new batteries or charge the Nuki Power Pack. You can find more information about batteries, rechargeable battery pack and the battery level here.
You can still lock your door from the outside with your key as long as your cylinder has an emergency or priority function. This means you can lock the door from the outside even if a key is inserted in the lock from the inside.
With our installation check, you can find out if your lock has this function.
