Try a battery disconnect for at least twenty minutes. Sometimes codes can be hard to erase and "hard dumping" is the only way to clear things down. If the code remains, you perhaps then have to look further.

Make sure you know the radio code before disconnection. You will also have to reset the clock.

See how you get on and please let us know the result.
