Smart roadster sam unit swap help

[albertros]

Hi,
Problem = Smart roadster headlights on all the time.

I have very little experience with the smart car. Even though there are no faults stored in the sam unit (acording to star C3) I suspect this is the fault.

Can I just clone the eeprom in the HC12 sam unit chip?

What address do I need to copy and paste? I have to tel my chip programer what address to read ect.

If I paste a virgin file will I need to re-prog the 3 button key?

Can someone send me the virgin dump so I have the option?

Sorry for all the questions.

Many thanks
