Hi All, went to start my 02 350Z import on Friday and the immobiliser wouldn't disengage, so it wouldn't start. Tried locking and unlocking, both keys, disconnecting battery and no joy! 
  
Had a mechanic plug in and said it was stuck in lock mode but that he couldn't deactivate. 
  
Any ideas as to how I can fix, or can someone recommend a specialist near St Albans? 
  
Many Thanks
