Ensure the battery is charged. Unlock car on the key fob. Turn key in ignition to position 3 (ignition fully on but not at start) for 30s to 1 min. Return to fully off for 30s. Back to position 3 for 30s, to off for 30s. Then turn key straight to start position, engine should now catch on the started.
This should reset the imobiliser. Needed after the car is jumped from another car if the battery has run flat because its french and so is afraid of work.
