only bought the car recently and it is fine except for the light,
I have been using the red key, whats the difference my old punto 55 had to blue keys.
Should I worry?
You need to get a new blue one cut asap, or you will naff your whole system up....you can get them cut in quite a lot of high street key cutting places now, for about £25. But make sure they make you a blue one, not just clone the red, or you will be in the same situation.
