How to remove ignition lock switch when it is stuck in the locked position

Ignition Lock Cylinder Control Actuator
If the vehicle is equipped with a floor mounted console gear shifter, it has a ignition lock cylinder control actuator system in the steering column as an added safety feature. The ignition lock cylinder control actuators purpose is to prevent the steering wheel from being locked when the transmission is in gear and the vehicle may still be moving. The column ignition lock system consists of a ignition lock cylinder control acutator, and a park position switch that is located in the A/T shift lock control switch. The ignition lock cylinder control acutator contains a pin that is spring loaded out to mechanically prevent the ignition key cylinder from being turned to the lock position when vehicle transmission is not in the Park position. If vehicle power is lost, and/or the transmission is not in the Park position the operator will not be able to turn the ignition key to the lock position and will not be able to remove the ignition key from the column. GM has had some problems with this , If you have the console shifter there is a micro switch that when put into park a linkage pushes on this micro switch closing the circuit to ignition lock cylinder control actuator allowing you to remove your key ! These linkages fall out causing this problem ,an have electrical wiring problems as well ! I fixed a 2006 Chevy cobalt that had this same problem by getting a used shifter assembly at the auto salvage year ! cost $20.00 . There mite be a access hole under the bottom of the steering column with a release button up inside !

FIRST OF ALL, TURN OFF RADIO,DISCONNECT NEGATIVE BATTERY CABLE. IF EQUIPPED WITH TILT STEERING COLUMN,REMOVE TILT LEVER.CAREFULLY REMOVE THE UPPER AND LOWER STEERING COLUMN COVERS. REMOVE THE 3 TAMPER PROOF TORX IGNITION SWITCH MOUNTING SCREWS USING SNAP ON TOOL TTXR15A2 OR EQUIVALENT. GENTLY PULL THE SWITCH AWAY FROM THE COLUMN AND REMOVE THE 2 ELECTRICAL CONNECTORS FROM THE IGNITION SWITCH. WITH THE KEY IN THE LOCK POSITION, DEPRESS THE KEY CYLINDER RETAINING PIN FLUSH WITH THE KEY CYLINDER SURFACE. ROTATE THE KEY CLOCKWISE TO THE OFF POSITION THE KEY CYLINDER SHOULD NOW BE UNSEATED. ROTATE THE KEY CYLINDER COUNTER CLOCKWISE BACK TO THE LOCK POSITION, AND REMOVE THE LOCK CYLINDER. ( TO INSTALL ) CONNECT THE ELECTRICAL CONNECTORS TO THE IGNITION SWITCH. BE SURE THE CONNECTORS ARE SECURELY LOCKED IN PLACE. MOUNT THE IGNITION SWITCH TO THE COLUMN 3 SCREWS FOR VECHICLES WITH THE TILT STEERING COLUMN THE SHIFTER MUST BE IN THE PARK POSITION AND THE PARK LOCK DOWEL PIN AND THE COLUMN LOCK FLAG MUST BE INDEXED BEFORE THE SWITCH IS INSTALLED. PLACE SHIFTER IN THE PARK POSITION. PLACE THE IGNITION SWITCH IN THE LOCK POSITION. THE SWITCH IS IN THE LOCK POSITION WHEN THE STEERING COLUMN LOCK FLAG IS PARALLEL TO THE IGNITION SWITCH TERMINALS. POSITION THE PARK LOCK DOWEL PIN OF THE IGNITION SWITCH SO IT ENGAGES THE STEERING COLUMN PARK LOCK SLIDER LINKAGE. APPLY A LIGHT COATING OF GREASE TO THE PARK LOCK DOWEL PIN AND THE COLUMN LOCK FLAG. POSITION THE IGNITION SWITCH AGAINST THE LOCK HOUSING OPENING ON THE STEERING COLUMN. BE SURE THE SWITCH PARK LOCK DOWEL PIN ENTERS THE SLOT IN THE PARK LOCK SLIDER LINKAGE INSTALL THE RETAINING SCREW AND BRACKET. TORQUE THE SCREW TO 26 INCH LBS. INSTALL THE STEERING COLUMN COVERS AND THE TILT LEVER IF REMOVED. WITH THE KEY CYLINDER AND THE IGNITION IN THE LOCK POSITION INSTALL THE KEY CYLINDER INTO THE SWITCH UNTIL IT BOTTOMS. RECONNECT THE NEGATIVE BATTERY CABLE AND THE CHECK THE IGNITION SWITCH FOR PROPER OPERATION OF HALO LIGHT SHIFT LOCK IF EQUIPPED AND COLUMN LOCK.ALSO CHECK FOR PROPER OPERATION OF THE IGNITION SWITCH ACCESSORY, LOCK OFF, RUN AND START FUNCTIONS.

the actuator inside the sterring column that the lock cylinder turns is boken, this is a very complex job and is not for the home tech without a factory service manual.

Removal & Installation

1. Disconnect the negative battery cable. Remove the upper steering column shroud by removing the self-tapping screws.
   
2. Unfasten the four bolts retaining the lower steering column shroud, then remove the shroud.
   
3. Remove the lock screw, and detach the ignition switch electrical connector.
   
4. Rotate the ignition switch lock cylinder to the RUN position.
   
5. Remove the two screws retaining the ignition switch, and disengage the ignition switch from the actuator.
   

To install:

NOTE A new replacement switch will be set in the RUN position as received.

1. Adjust the ignition switch by sliding the carrier to the ignition switch run position.
   
2. Check to make sure the ignition switch lock cylinder is in the RUN position. The RUN position is achieved by rotating the ignition switch lock approximately 90 degrees from the LOCK position.
   
3. Install the ignition switch assembly into the column actuator hole. It may be necessary to move the ignition switch slightly back and forth to align the ignition switch mounting holes with the lock cylinder housing threaded holes.
   
4. Install the retaining screws and tighten to 53–71 inch lbs. (6–8 Nm).
   
5. Attach the electrical connector to the ignition switch. Tighten the lock screw to 7–11.5 inch lbs. (0.8–1.3 Nm).
   
6. Connect the negative battery cable. Check the ignition switch for proper function, including the START and ACC positions. Also, make sure the column is in the LOCK position.
   
7. Install the upper and lower steering column steering shrouds.
   

Removal & Installation

1. To prevent accidental air bag deployment, disconnect the negative battery cable, then the positive battery cable to allow residual energy in the air bag system to drain.
   
2. Remove the steering column shroud(s).
   
3. Disengage the wiring harness connector from the ignition switch.
   
4. Insert the key into the ignition switch, then rotate the ignition key lock cylinder to the RUN position.
   
5. Remove the two screws attaching the ignition switch.
   
6. Disengage the ignition switch from the actuator pin and remove the switch.
   

To install:
A new ignition switch purchased from Ford will already be set in the RUN position.

1. Adjust the new ignition switch by sliding the carrier to the RUN position.
   
2. Check to ensure that the ignition key lock cylinder is in the RUN position. The RUN position is achieved by rotating the key lock cylinder approximately 90 degrees from the LOCK position.
   
3. Install the ignition switch onto the actuator pin.
   
4. Align the switch mounting holes and install the attaching screws. Tighten the screws to 50-69 inch lbs. (6-8 Nm).
   
5. Attach the electrical connector to the ignition switch.
   
6. Connect the positive, then the negative battery cables. Check the ignition switch for proper function in START and ACC positions. Make sure the column is locked in the LOCK position.
   
7. Install the steering column shroud(s).

IGNITION SWITCH

1. Remove the steering wheel, then remove the steering column covers.
2. Disconnect the 7-P connector from the under-dash fuse box.
3. Insert the key and turn it to "0."
4. Remove the 2 screws and replace the base of the switch.

The "SPRING-BACK" Action is Originated in the Ignition Switch itself (THE ELECTRICAL SWITCH) I think that is where you should Look. On these models, the ignition lock and ignition switch are removed as an assembly. Refer to IGNITION LOCK .
Disable airbag, refer to Air Bags and Seat Belts/Air Bags (Supplemental Restraint Systems)/Service and Repair . After procedure has been completed, rearm airbag system.

I have 07 Pontiac Grand Prix, the wrong key was inserted into the ignition the other day. Now when I try to use the correct key it will not insert completly in the ignition, goes in until last 1/4in of key. Im stuck, I bought the new lock cylinder but how do I get the old one out? I cant get the key to insert all the way so I cant get it to the "On" position, it will not turn at all. The key that was inserted in error is whole and nothing is missing it seems like there is something stuck. Any help would be appreciated...
