sounds like van is in theft mode. you can try to see if the key will relearn it self, by putting the key in the ingnition turn to on and let set for 10 minutes or a little longer. Then try to start. If this dosen't work you may need to replace the lock cylinder and key. or have reprogramed with a TECH II scan tool.
