that is great, thanks!
Can you just give me a hint where I can find that box? The last time I had a look I didn't see it
Edit: if I have a look in the Y61 technical manual, on page EL 260 there is a 'super lock control unit' - is that the one I am looking for?
Theoretically that would be the only item I have to exchange if I wanted to get a new remote lock system, isn't it? Or must I look for the multi remote control unit I can see on page EL 330?
