Hello , thanks for your question in the autoaid Community.
Your described fault Code means: ENGINE CONTROL UNIT BLOCKED BY IMMOBILISER
Possible cause:
control unit for ignition fuse blown / missing short circuit of the communication line wrong encoding manipulation attempt
possible impact: running engine
troubleshooting: engine control unit fit the electronic drive-away protection
Maybe your Key is faulty, test it with the second key
