Key in Ignition Audible Chime
WARNING: This page is about a different car, the 2003 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
The ignition key must be seated and rotated before a chime will occur. The BCM will provide an audible chime if the key is left in the ignition in either OFF or Accessory position with the drivers door open. The chime rate for this chime is 150 chimes per minute. The key in ignition chime has a higher priority than the lights on chime.
