I`m afraid that you are going to have to extract the radio from the dashboard and quote its MAKE , MODEL and ALL the SERIAL NUMBERS on the casing in order for someone on here to calculate your Security KeyCode. If you don`t have the correct tools , then inserting 4 pieces of wire(using a wire coathanger perhaps) /or 4 small screwdrivers /allen keys into the 4 holes on the front (at the SAME TIME) whilst an assistant pulls the radio out of the dashboard sometimes works....Very fiddly though. If not , cheap extractor keys are available on Ebay.
