Forgot to add 2 hrs later .... when spare Key opened the Acadia. Newly purchased jumper cables applied jump power instantly the key was able to be removed from the ignition.Wife drove 2009 Acadia to the Grocery store. Returned from shopping and raised Liftgate with remote fob, loaded groceries closed liftgate. Attempted to start the Acadia. Just clicking noise then nothing. Battery dead. Unable to extract key from the ignition once the battery dies. Couldn't lock and close doors to seek help since key was stuck in the ignition and no spare currently in town. While stuck the Key would turn to Start Engine position, Not to accessory, It would not allow it's removal from the ignition no matter what was tried. Attempted to get Jump cable from rear trunk area. Can't open liftgate, No Power. Cargo area full of cargo so you can't raise floor to get to rear trunk area to retrieve jumper cables.
Leaves her stranded with no way to securely lock the Acadia except to lock her keys inside while she goes to get assistance.
Once the Acadia is locked, assistance must now come from someone who has a spare key for this Acadia and is located 50 miles away.
Why couldn't the Key be extracted from the ignition without battery power.
How can a person open the liftgate when there is no battery power?
