There is a known problem with the balts keeping the keys. The shifter (if it's automatic) has a switch made inside of it that tells your BCM that you have it in park. When it sees this, it will release the key. Sometimes this switch goes bad and you can't get your key out of the cylinder. The whole shifter has to be replaced to fix this.

--------------------------------------------------------------------------------

This bulletin is being revised to add models and model years. Please discard Corporate Bulletin Number 06-07-30-004B (Section 07 - Transmission/Transaxle).



--------------------------------------------------------------------------------

Condition
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 Floor Shifter 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.

Happens to me on and off...not worth the time to take back to the dealer for fix. Most of the time I just jiggle the gear shift lever while it's in Park for the key to release.

Dealer fixed it for me in a day along with realigning my right side after someone hit me in a parking lot.

I've been having the same problem with the key not releasing from the ignition for about two weeks now, about the same time I had a spare key made and used the spare a few times then continued to use the original key.

I found the release button under the ignition switch (removed the access panel) and sprayed some Liquid Wrench on the release button and worked the key back and forth several times and so far so good!!!

I don't think my problem was related to the shifter at all, I think the spare key did something to the ignition cylinder, metal filings or something like that.

We'll see how long this quick fix with the lubricant lasts!!!
