I cant get my shifter to move out of park, i just replaced my ignition lock cylinder could it be some type of theft prevention?

Do any of the light's work ? Headlamps ? Battery in good working order ? Have you tried to jump the car ? Does the key go all the way to off ? Does it have shifter on the floor ( center console ) ?
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. The ignition lock cylinder control actuator's purpose is to prevent the ignition key from being turned to the OFF position 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 actuator , and a park position switch that is located in the A/T shift lock control switch. The ignition lock cylinder control actuator 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.

Is it shifter on the floor ?

GM had problems with these ! Has a TSB - technical service bulletin !
Automatic Transmission Shift Lock Control Description and Operation
The automatic transmission shift lock control system is a safety device that prevents an inadvertent shift out of PARK when the engine is running. The driver must press the brake pedal before moving the shift lever out of the PARK position. The system consists of the following components:
• The automatic transmission shift lock solenoid (serviced as the automatic transmission shift lock actuator), as well as the body control module (BCM) and the engine control module (ECM). The shift lock solenoid is located within the floor shift control assembly with vehicles equipped with floor shift.
• The BCM controls the voltage to the shift lock control solenoid through the shift lock control solenoid controlled voltage circuit. The following conditions must be met before the BCM will remove voltage from the shift lock solenoid:
- The ignition is in the ON position.
- The engine control module (ECM) sends an input via GMLAN serial data to the BCM indicating the transmission is in the PARK position.
- The BCM determines the brake pedal is applied according the brake pedal position.
Since the shift lock control solenoid is permanently grounded, the BCM supplies voltage to the automatic transmission shift lock control solenoid, mechanically locking the shift lever in the PARK position as the solenoid energizes. When the brake pedal is applied, the BCM turns the control voltage output of the shift lock control solenoid OFF, de-energizing the shift lock control solenoid. The de-energized solenoid releases the mechanical lock allowing the driver to move the shift lever out of the PARK position. When the transmission is out of the PARK position, the shift lock control solenoid remains de-energized.
During remote start operation, the BCM will energize the shift lock control circuit, locking the shift lever in the PARK position.
Replaced shifter on a cobalt , broken plastic part inside , wouldn't press on micro switch to disengage ! Found replacement shifter at auto slavage yard .$20.00 US

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 !

Does it go into the lock position ? Will the shifter go into the park position ? Is it a automatic transmission ?
Electronic Park Lock (EPL)/Ignition Lock Cylinder Control Actuator: If the vehicle is equipped with automatic transmission and a floor mounted console gear shift, it has an ignition lock cylinder control actuator system in the steering column. The ignition lock cylinder control actuator purpose is to prevent the ignition key from being turned to the OFF position when the transmission is in any position other than PARK and the vehicle may still be moving. The column ignition lock system consists of an ignition lock cylinder control actuator, and a park position switch that is located in the automatic transmission shift lock control switch. The ignition lock cylinder control actuator contains a pin that is spring loaded to mechanically prevent the ignition key cylinder from being turned to the lock position when the 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.
There should be a hole in the bottom of plastic steering cover or a rubber cover that comes out . you can stick your finger up there an there is a button you push that will allow you to take out the key !

replace the shifter assembly.I replace alot of them.use this bulletin as a reference.Subject: Various Concerns With Shifter and/or Ignition Key (Replace Shifter Assembly/Shifter Components or Ignition Lock Cylinder )


Models: 2005-2008 Chevrolet Cobalt

2005-2006 Pontiac Pursuit (Canada Only)

2007 Pontiac G5

with Automatic Transmission 4T45-E (RPO MN5)

Some customers may comment on any of the following concerns:

• The shifter is hard to move or binds.

• They cannot remove the ignition key.

• It takes high effort to rotate the key.

Cause 1
The shifter button may be sticking in the handle.

Cause 2




The pin that activates the micro-switch may have moved out of position (refer to illustration above). This causes the micro-switch to fail to engage when the vehicle is placed in Park. If this condition is present, the customer will not be able to remove the key from the ignition.





The illustration above shows the switch in a correct position.

Cause 3
Metal flashing left in the cylinder may cause a high effort to rotate the key.

Cause 4
The slider may be binding in the guides. This may cause the shifter to become difficult to operate.

Correction 1
Verify that the shifter button is inoperative by evaluating if the park pawl pin on the shifter assembly moves when activating the button. If the parking pawl does not move when the button is activated, the shifter handle will have to be replaced. Refer to Floor Shifter Control Knob Replacement in SI.

Correction 2
Important: A change has been made to the shifter assembly for service. The replacement shifter assembly will read PRNDIL (Park, Reverse, Neutral, Drive, Intermediate and Low).

Verify that the micro switch is out of position. Replace the shifter assembly. Refer to Transmission Control Replacement in SI.

Correction 3
Important: Refer to instruction sheet that is supplied with the lock cylinder kit. BO 47869 is an essential staking tool and must be used for the repair.

Replace the ignition lock cylinder. Refer to Ignition Lock Cylinder Replacement in SI.

Correction 4
Replace the slide indicator and guides in the shifter following the procedure below:

Apply the parking brake.
Remove the upper console trim. Refer to Trim Plate Replacement-Console Front in SI.
Remove shifter knob. Refer to Floor Shifter Control Knob Replacement in SI.
Remove the indicator plate. Use a flat-bladed screwdriver to release the locking tabs.
Remove the shifter indicator lens.
Pull up on the indicator and remove it from the assembly.
Remove the two front rails by unsnapping the front and lifting up, and then back, to remove the rails from the shifter assembly.
Install the new guides. Place the hook end into the assembly and push down. It will snap into place.
Install the new slide indicator. With the transmission in neutral, place the slide over the shifter and into the guides. Move the slide indicator down the guides in the front and rear.
Important: Replace the shifter indicator lens if damage is present due to the slider binding or if it becomes damaged during disassembly.

Install the shift indicator lens.
Install the shift indicator plate.
Install the shifter knob. Refer to Floor Shifter Control Knob Replacement in SI.
Install the upper console trim. Refer to Trim Plate Replacement-Console Front in SI. post back with what you find.
