Lincoln navigator 2004 rear door not working - Lincoln Cars & Trucks

SOURCE: Problems with Gearshift 2004 Lincoln Navigator

Turn the key forward a notch then it should come out. If you are turning the key all the way off it enables the accessories (radio etc), locks the key in the ignition and disables the gear shifter.
If thats not the case then there is a button to be depressed so that the key can turn anticlockwise>off another click and the key can be removed.
It'll be one or the other....faulty ignition lock is the only other diagnosis
