Title: "Maxx" keys
Post by: Sarver Systems on November 04, 2013, 10:09:00 am

How exactly do these work?

For example, what makes one key different from the others?

I could understand if it had come circuitry inside it, but this thing only has an in and out.

The only thing I can think of is that it resonates a certain frequency or something.

Is there some way to reprogram them from an older version (ruby) to a newer version (jade)?

So its possible that these Dallas Keys can go dead if they aren't used for quite a while?

I dont have a maxx key to verify, but you could use ibcm (ibutton copy machine) to backup your key. You would need a DS9097U-S09/009 to read it out though.
