Hi,
As suggested I have followed the instructions. EXISTING FOB, HORN SOUNDS, ADD FOB....A message appears saying add 21 digit code and last digit will be generated check last digit is correct.

The screen appears as attached. There are two buttons on it that appear to be a zero, the other N. If I have the 22 digit code correct it starts with at C66382 etc not zero or N

So faced with no other clues I can click zero or N and a square of buttons appear ( What is zero or N option?) do I delete and type in the 21 digits or leave the zero or N at the start?

I can also click in the message square and type in the code....there is nothing to suggest this is correct?
