You can try '1234' or '0000'... That was the factory default security numbers on the 451's for years.
Maybe this will help. I found a company that lists codes for smart radios based upon model.I had to change my battery after coming home from a long vacation, when the new battery was put in, my radio asked for a passcode, now it's telling me to call my service person, I live on an Island, we do not have a "Smart Car" service facility. Can anybody tell me what my next move is??? it's a 2014 gas smart car
thank you

I cannot say, but my intent was to provide widest breadth of information, since some people may visit Europe and return with gray market radios.D
