So I recently bought a nissan micra. Radio needed a code, which the dealer I got the car from didn't have. Decided to pop into my local nissan dealer to see if they could help. Got told I would have to pay £50 for the code. So I said to the guy don't worry I'll just get another stereo fitted. To which I was told I couldn't do that as if I disconnect the factory fitted stereo I'm taking out an element to the immobiliser. He then went on to tell me how people have gone to Halfords and they then get phone calls asking why the car won't start. I think someone is spinning me a line. Seriously annoyed me though not the experience I was expecting to receive. I had the same issue with my last car a renault scenic popped into the main dealer was given a code no charge.
