Ignition Key
Unable To Remove Ignition Key
1. Check if the inability to remove the key is the result of normal operation of the key inhibit removal circuit: In automatic transmission equipped vehicles, the key removal inhibit solenoid (within the ignition switch assembly) is energized when the gear selector is moved out of the park position, amd prevents the ignition key from being removed.. If the gear selector is in any position other than park when the key is rotated or turned off, the key removal inhibit circuit will not release the key (key cannot be removed). To remove the key, the gear selector must first be placed in the park position, then the ignition must be cycled to run and back to lock. This is normal, do not replace the ignition lock cylinder iuf it is operation as described.
2. Refer to: Transmission and Drivetrain; Automatic Transmission/Transaxle; Shift Interlock, A/T and follow diagnostics for the "shift interlock system". The shift interlock system includes the key removal inibit circuit, which may be causing the concern. If the shift interlock system is operation correctly, replace the ignition lock cylinder. Refer to: Ignition Lock; Service and Repair; "Ignition Lock Cylinder - Functional" removal and installation proceure.
