Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in "Park" and the battery is disconnected to prevent electrical shorts.
Tools Required:
- Screwdriver set
- Lubricant (graphite-based)
- Pliers

2. Inspect and Lubricate the Ignition Cylinder

Remove the plastic cover surrounding the ignition switch using a screwdriver.
Apply graphite lubricant into the ignition cylinder to improve the key's movement.
Insert the key and gently work it back and forth while turning to see if it engages.

3. Check the Steering Lock

If the key still won't turn, try to wiggle the steering wheel back and forth while simultaneously turning the key.
If successful, this indicates the steering lock was engaged and can be avoided in the future by ensuring the wheel is not turned too far when parking.

4. Replace Ignition Cylinder (if necessary)

If lubrication does not resolve the issue, you may need to replace the ignition cylinder.
Disconnect the battery entirely before proceeding.
Remove the ignition switch retaining screws and disconnect the wiring harness.
Install the new ignition cylinder by reversing the removal steps and reconnect the battery.
