"Maxx" keys

Sarver Systems:
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)?

Sarver Systems:
