Renault Clio 1.2 16V Dynamique 2003 Hazzard switch removal from dash board?

Hi,

Can you please tell me how to physically remove my faulty hazzard switch from the dashboard so I can inspect it and repair/replace ?

Also, I may need to change my battery, I cant find my radio code from my paperwork. Is there a way to get the code from the radio before I change the battery ? also are there any other codes (eg) immobiliser, engine management system code that I may need before I change the battery ?

your help is much appreciated,

Jeff in Swindon
