Remove or transfer your lock, or switch phones

In this article you can read how to remove a lock from the app, what to do when you get a new phone, and how to transfer a lock to someone else.


Remove a lock from the app


  1. Open the app and press the menu button at the top right of the home screen.
  2. Press "Lock settings".
  3. Choose the option to remove the lock and follow the steps on the screen.


Can't remove the lock, for example because you have already sent it back? Contact support and we will remove it for you.


New phone


Your lock is linked to your account, not to your phone.

  1. Download the app on your new phone.
  2. Log in with the same email address you used on your old phone.
  3. Allow the app permissions (Bluetooth and location).
  4. Your lock will appear in the app automatically.


Transfer a lock to someone else


  1. Remove the lock from your own app (see above).
  2. The new owner downloads the app, creates an account and pairs the lock via "Add lock".
  3. The new owner sets their own emergency code during pairing.


Only want a friend or family member to use the lock? Then you don't need to transfer it. You can share the lock via "Share" in the menu.


Received a replacement lock


Received a replacement lock? First remove the old lock from the app, then add the new lock via "Add lock".
