Hi
Chap in France I have just sold my car to - he reports the spare key will start car but will not operate locks etc when button is pressed. Has changed battery, no joy, and asks if it needs programming. I honestly cant recall whether I tested it after I bought the car last year, I think I did and if I did then it will have worked at the time and I had not been concerned or minded to check it before I drove the car to France earlier this week.
Any tips for reprogramming or what options does he have for repair or replacement? He has the codes with the docs.
