So one of my switchblade keys was stolen. In order to make the old keys non-functional with my car (locks & ignition) what do I need to do? Will they need to put a new lock cylinder in the door and the ignition? So frustrating if they do, i just had the driver's side lock cylinder replaced because someone messed with it and broke into my car a few months ago. GRRRRRR! I have a 2001 Jetta TDI.
