some people know the codes you need you'll need the make of the radio for them to help you. we lost our code like that beware after 20 goes it locks you out permanently.
State make, model and serial no. (on radio case) and post on here, someone will help you..
We had the same problem with a rover 200, if you look on ebay you can get a decoding service for 拢5, worked fine for us, hope that helps
