Just copy eeprom data from original to new ews & use original key.

Use this dump (rolling code reseted):

I think you should pinpoint the problem via diagnosing tools first.
If problem is between Key& EWS or between EWS&DME. Diagnosis will tell you for sure what the problem is.

If engine cranks but doesn't start: problem most likely is EWS-DME sync or isn. Could be faulty DME that has for some reason lost or corrupt ISN. In that case new EWS won't solve your problem.

If engine doesn't crank then problem is KeyData-EWS.
In that case (key-ews) you could get a blank transponder and write it to match ews. Or reset random code (setting values to FFFFFFFFF in dump) and try using your current key if you don't want to waste a transponder.

I don't understand what you mean by 'who please create a new key data'
