1. A method, comprising:

  • generating, by a wall-mounted control panel of a security and automation system of a structure at a first location, a first unique identifier for the wall-mounted control panel based at least in part on detecting a first biometric identifier of a user at the wall-mounted control panel, the wall-mounted control panel being positioned in the structure of the security and automation system;

    transmitting, by the wall-mounted control panel, the first biometric identifier to a server at a second location remote from the first location of the wall-mounted control panel;

    entering a locked state when the wall-mounted control panel is reformatted by altering the software or hardware of the wall-mounted control panel;

    locking the wall-mounted control panel according to a first lock mode in response to an unauthorized takeover and based at least in part on entering the locked state, the first lock mode being different from a second lock mode of the wall-mounted control panel, wherein the first lock mode prevents a user from accessing the security and automation system and/or the wall-mounted control panel and the second lock mode allows a user to access at least a portion of the security and automation system and/or the wall-mounted control panel upon entering credentials;

    detecting an authentication code on an external storage device;

    comparing the detected authentication code with an authentication code stored locally on the wall-mounted control panel;

    approving the external storage device when the two authentication codes match;

    receiving a second unique identifier associated with the wall-mounted control panel from the external storage device using a universal serial bus (USB) drive of the wall-mounted control panel and based at least in part on a second biometric identifier after locking the wall-mounted control panel according to the first lock mode, the second unique identifier being an authenticated version of the first unique identifier that is authenticated by the server;

    transitioning from the first lock mode to the second lock mode based at least in part on the wall-mounted control panel validating the second unique identifier, wherein validating the second unique identifier comprises determining, at the wall-mounted control panel, that the first unique identifier, stored locally on the wall-mounted control panel, and the second unique identifier, received from the external storage device, match;

    unlocking the wall-mounted control panel from the first lock mode based at least in part on transitioning from the first lock mode to the second lock mode; and

    opening a profile associated with the second biometric identifier after unlocking the wall-mounted control panel, wherein the second lock mode is based at least in part on the profile associated with the second biometric identifier, wherein the profile comprises a user profile and unlocking the wall-mounted control panel enables the user to access a portion of the security and automation system using the wall-mounted control panel.
