Solution

1. Preparation

Gather tools such as a flathead screwdriver, a flashlight, and an OBD-II scanner.
Ensure the vehicle is in park (automatic) or neutral (manual) with the parking brake engaged.
Disconnect the vehicle battery to avoid electrical issues.

2. Inspect the Steering Lock Mechanism

Attempt to gently turn the steering wheel in both directions while trying to turn the key.
If the steering lock is engaged, this may release tension and allow the key to turn.

3. Check the Ignition Key

Examine the key for signs of bending or excessive wear.
If damaged, replace the key with a new one programmed for your vehicle.

4. Inspect the Ignition Cylinder

Use a flashlight to look inside the ignition cylinder for debris or foreign objects.
If debris is found, use a flathead screwdriver to carefully remove it.

5. Test the Ignition Switch

If the key still does not turn, check the ignition switch functionality. Remove the plastic cover around the ignition switch.
Use a multimeter to test the ignition switch for continuity when the key is in the ON position.
Replace the ignition switch if no continuity is detected.
