Answer
Hi Steve, The jerking problem first..Disconnect the EGR valve and drive it..remove the vacuum hose from the valve. If it doesn't do it now replace the valve. I'll bet your buying a valve.

   The pass key.....You need a new ignition lock cylinder. There is no way to disconnect this that I know of.

Have a  Nice Day        Mark
