I have had the Vivint Sky Panel installed for almost a year now. When I first got the system I was not very educated on the whole diy security system. For the most part I am happy with the system but I do wish I could add sensors and accessories myself. I understand that I will not be able to do a full takeover with this panel. But what I am wondering is, if I call out Vivint to install a new door sensor on a detached garage will I then be able to use the 2203 installer code after he leaves to disable the 48 hour lock.
