Hi I'm looking to get my code for my radio as had new bat...

Hi! This is Anthony, a mechanic here on Just Answer. Sorry to see you're having trouble with your radio. Unfortunately, the mechanics on Just Answer are no longer able to provide radio codes, pin codes, etc. These security measures were put into place to protect vehicle owners like yourself from theft. If you can't locate the code in the vehicles manual or sticker on the glove box, your local Nissan dealer can provide you with the code. I recommend contacting the parts department as they are usually the easiest to deal with. I'm sorry, I know this isn't the answer you were hoping for. However, we need to follow policy to ensure all our customers are protected from theft. If I can help in any other way with the radio, please don't hesitate to ask. Thanks for choosing Just Answer and enjoy your weekend.

after that will I get my £5 back

I'm just the mechanic but will refer this to customer service now. Thanks!
