DSC now uses some type of algorithm with their panels. The firmware chip
also has a built in eprom which generates a code, which then must match
the code stored in the eprom used to store the data. I haven't had time
to play with it, but I am sure we will figure it out soon enough.

The manufacturer will never do something that will also prevent
themselves from accessing a locked panel.

It's not rocket science.
