Customer Questions & Answers

  1. Answered by the admin

    This lockbox does not require a Wi-Fi connection as it communicates to your smart phone via Bluetooth connection when within range.

  2. Q Can it be an unlimited amount of manual entered codes? answer now
    Asked by A.J. Schroeder on April 4, 2020 6:38 PM
    Answered by the admin

    Only the Primary Code, the current Temporary Code, or the Backup Master Code can be manually enrolled. All other credentials are enrolled via the mobile app. 

  3. Answered by the admin

    Yes, you are able to assign multiple codes to this unit and track which codes were used and at what times.

  4. Answered by the admin

    The override code for these units can be changed from within the Masterlock Vault App by selecting your lock to view details and going to the Settings tab. Here, you should see the option to enroll primary and secondary codes.
