Troubleshooting Steps: 2012 GMC Acadia Key Stuck In Ignition

Now that we’ve identified some potential causes of the 2012 GMC Acadia Key Stuck In Ignition, let’s move on to the solutions. Follow these troubleshooting steps to regain control of your 2012 GMC Acadia:

1. Inspect The Battery

To ensure that the battery in your 2012 GMC Acadia has enough power to operate the electrical components properly and potentially resolve any issues with the key release mechanism, follow these steps:

Step Description
1 Open the hood and locate the battery in the engine compartment.
2 Inspect the battery terminals for corrosion (white or greenish deposits). Corrosion can affect battery performance.
3 Measure the battery voltage using a multimeter or battery tester. Connect the positive (red) and negative (black) leads to the corresponding battery terminals. The voltage should ideally be around 12.6 volts or higher for a fully charged battery.
4 If the voltage is significantly lower than 12.6 volts, the battery may be weak or discharged. Consider jump-starting the vehicle with jumper cables and a second vehicle with a functioning battery.
5 Connect the positive (red) jumper cable clamp to the positive terminal of the dead battery. Then, connect the other end of the positive jumper cable to the positive terminal of the functioning battery.
6 Connect the negative (black) jumper cable clamp to the negative terminal of the functioning battery. Attach the other end of the negative jumper cable to a metal surface or grounding point on the vehicle with the dead battery, away from the battery itself.
7 Start the vehicle with the functioning battery and let it run for a few minutes to charge the dead battery.
8 Attempt to start your 2012 GMC Acadia. If the weak battery affected the key release mechanism, it should now function properly.
9 If the battery doesn’t hold a charge or continues to cause issues with the key release mechanism, consult a professional or refer to your vehicle’s owner’s manual for guidance on battery replacement.

2. Lubricate The Ignition Cylinder

Over time, the ignition cylinder can become worn and stiff, making it difficult to turn the key.

Applying a lubricant, such as graphite powder or a silicone-based lubricant, can help reduce friction and make it easier to turn the key. Follow these steps to lubricate the ignition cylinder:

Step Instructions
1 Clean the key: Wipe the key with a clean cloth or use a small brush to remove any dirt or debris.
2 Apply the lubricant: Spray a small amount of silicone spray onto the key OR dip the key into graphite powder, ensuring even distribution of the lubricant on the key’s surface.
3 Insert the key: Insert the lubricated key into the ignition cylinder.
4 Gently turn the key: Turn the key back and forth several times in a gentle manner to distribute the lubricant throughout the cylinder and coat the internal components.
5 Wipe off excess lubricant: Use a clean cloth or paper towel to wipe off any excess lubricant that may have accumulated.

3. Check The Steering Wheel

To check the steering wheel and ensure it’s not causing the key to be stuck in the ignition.

Follow these steps:

  1. Sit in the driver’s seat and make sure the vehicle is in the park.
  2. Place your hands on the steering wheel at the 9 o’clock and 3 o’clock positions.
  3. Try to move the steering wheel back and forth gently while simultaneously attempting to turn the key in the ignition.
  4. If the steering wheel is locked, you may feel resistance. Apply slight pressure in the opposite direction of the lock while turning the key.
  5. Continue trying to turn the key while gently maneuvering the steering wheel until you feel it start to release.
  6. Once the tension is relieved, the key should turn freely, allowing you to start the vehicle or remove the key from the ignition.

Remember, it’s important to be gentle when manipulating the steering wheel to avoid causing any damage.

4. Verify The Gear Shift Position

To verify that your vehicle is in the park position, and smooth running of the vehicle follow these steps.

Verify the Gear Shift Position
1. Ensure that your foot is firmly pressing the brake pedal to enable proper shifting.
2. Look at the gear shift lever on your vehicle’s center console or steering column.
3. Locate the indicator that shows the different gear positions (P, R, N, D, etc.).
4. Check if the indicator aligns with the “P” or “Park” position. This indicates that the gear shift lever is in the correct position for removing the key from the ignition.
5. If the gear shift lever is not in the park position, wiggle it back and forth gently while maintaining pressure on the brake pedal.
6. As you wiggle the gear shift lever, listen for any clicking sounds or feel for any slight movements.
7. Repeat the process of wiggling the gear shift lever while pressing the brake pedal until you hear or feel a click or until the lever firmly engages in the park position.
8. Once the gear shift lever is securely in the park position, try to turn the key in the ignition or attempt to remove the key.
