Correct, proximity will be ok. As to new card, you buy a card for your car, that's it, simple..Hy Ian,
Thanks for your inputs. Well, this is just a 2nd emergency card so the 7947 should work just fine for that.
When I'm going to program it for the car I'll need to program the new card and the old one again. I'll not loose the proximity sensor for the old one?
What about the new card, it cames precoded to the car. How is that possible? I have to tell the seller some info about my car?
Just program all keys via OBD2 and all ok
