I have 2 keys. The Red H key is bigger than the non Red H key. What are the difference between it? Does 1 have a immobiliser and the other dont? Or is it just size and nothing else.
Mine came from Japan with 2 keys just like that, think the black one is just a spare made by an owner at some point.
I always carry around and use the black one, just in case I ever lose my keys its not obvious that it'll start a type R and not just any other honda in the parking lot lol
