Hi All, I have done an auto scan of all mudules. And now want to change the long coding so that the car chirps when alarming / disarming with the remote. The thing is, I know how to change the long coding. And what it currently is, but I don't understand it. Not one bit. what do all the nikbers mean? I have got the link to the page that has all the coding options etc and what bits are what etc. And I'm stuck. This is the original coding from my car 1980200002186D0985054C9FC637 so what does what and what do i change? anyone?
