Solution

1. Preparation

Gather tools: screwdriver set, lubricant (e.g., graphite spray), and cleaning cloth.
Ensure the vehicle is in "Park" or "Neutral" and the parking brake is engaged for safety.

2. Check Steering Lock

Attempt to move the steering wheel left and right while gently turning the ignition key. This may release the steering lock.
If it does not release, check for any obstructions in the steering column area.

3. Inspect the Ignition Key

Examine the key for any signs of bending or damage. If damaged, replace the key.
Clean the key with a cloth to remove dirt or debris.

4. Clean the Ignition Cylinder

Use a can of compressed air to blow out any debris from the ignition cylinder.
Apply a small amount of graphite lubricant into the ignition cylinder to ensure smooth operation.

5. Test the Ignition Switch

Disconnect the battery to avoid any electrical shorts.
Remove the lower steering column cover using a screwdriver.
Locate the ignition switch and use a multimeter to check for continuity when the key is turned to the "On" position.
If the switch is faulty, replace it with a new ignition switch.

6. Reassemble and Test

Reinstall the steering column cover and reconnect the battery.
Test the ignition key to ensure it turns smoothly and starts the vehicle.
