I’m sorry for the delay. You may follow the steps below using the Nest app to change your pass code:
On the Nest app home screen, tap Settings .
Tap Family & Guests .
Tap You to change your own passcode.
Tap Passcode. If you sign in with a Nest Account, you’ll enter your account password, minimize your phone’s keyboard, and press Continue.
Enter a passcode you’ll remember between 4 to 8 digits long. Note: If another person is using this passcode, a notification will pop-up to prompt you to Choose a different passcode. Passcodes must be unique so you can see who locked and unlocked your lock in History .
Tap Show passcode to view the passcode.
Tap Save. If you sign in with a Google Account, you’ll receive an email that your passcode has been changed.
Just checking in to make sure that you've seen our responses. Please let me know if you have other questions or concerns as I will be locking this in 24 hours if I won't hear back from you again. Feel free to start a new thread and we'll be happy to help.
