Morning ! I used PASoft 1.4.0 to read the faults and diagnose all the issues. If you can run a live dianosis, when you insert the key into the ignition and turn one click, you should see the ews read the transponder in the key and go green, showing the code is a match. My key fob transponder failed and stopped the car starting.
the ews has a rolling code that changes every time the car is turned off. Can you try with another key?
with pasoft, you can reset and re sync the dme and ews units to correct some issues.
