• All you need to do is get the blank blade cut and program the transponder to  your immobiliser, which can ONLY be done by professionals.
  Please make sure before purchase that chosen specialist will be able to get it  coded for you.
  We can't code this key for you as we don't have the equipment.
   
• REMEMBER - YOU WON'T BE ABLE TO START THE ENGINE BEFORE IMMOBILISER IS CODED!!!!!!
  This process is the same with any key you buy from anywhere else.
   
• Please check compatibility before buying if you don't know how to do that - CHECK HERE

  ONCE AGAIN - this is remote coding procedure NOT transponder/immo coding
  transponder/immo coding must be done by specialist via special tools.
