Answer
I am not sure if the factory security system on your vehicle even offers starter kill, but here is something to try.  Above your glove box, behind the ABS control module is your 'theft warning module'.  At this module you will find a lt. blue wire, this lt. blue wire serves as the factory alarm disarm wire.  In a properly working vehicle, this wire goes to ground when you unlock the door with a key.  If you ground this wire permanently the security system will not arm.  However I do not know if this would cause any other unwanted behavior.  Some systems illuminate the dome light when there is ground provided to the disarm wire, if for some reason your system does behave oddly after grounding this wire, I would recommend adding a momentary switch inline between the ground and this wire.  This would allow you to disarm the alarm by simply pushing the button.
