Sorry, for the necropost! I found this forum by accident and thought since none of you guys found an answer in all those years, I could clear this up for you and maybe help someone who lost the manual. If you'd like, I can even translate the part of the manual where it said how to program it.

I think you're right about the zombie thing since my remote is over 10yo and slowly falling apart. But it's still functional. How did you know?
