I have the triple threat in my 05 with outlook monitor,how do i completely remove the program?

This is a direct quote form BD.com;
From the on the fly screen navigate to the main menu and enter the download option. At this point make sure the vehicle is OFF. Then press 'N' to completely return the vehicle to stock. The counter on the screen tells how far along the return to stock process is; once finished, unplug the t dog and recycle the key.

My screen is only on when the key is turned on,will it still work?
