Don't get your key from a Dealership!!!! How much $850 plus $100 to program it?? Needswings.com will get you one for ALOT less. Also YOU can program that key yourself. Search on the forum for "programming your own key". I don't believe the key is your problem with the starting issue. The starter should continue to turn over until the car starts. Are you saying it disengages ,before it starts?
