Greetings,
Did you ever figure this out? I'm in the same boat, the pass phrase must be simple and based on the account or service address ect. something the tech could figure out by the information he has with him on the service call.
i have a door sensor i want to remove from the system.
i figured out the code to get into the installer part on my own, i will not give up on this pass phrase until i get it
