2
Inspect the ignition key for damage or wear; try using a spare key if available.
3
Verify that the gear shift is fully in the 'Park' position.

Solution

1. Preparation

Tools Required:
- Flathead screwdriver
- Lubricant (such as graphite or silicone spray)
Ensure the vehicle is in a safe location with the parking brake engaged.

2. Check Steering Lock

Attempt to turn the steering wheel back and forth while gently trying to turn the key.
If the key still does not turn, proceed to the next step.

3. Inspect the Key and Ignition Cylinder

Remove the key and visually inspect it for bending or wear.
If the key appears damaged, use a spare key.
If the spare key also fails to turn, inspect the ignition cylinder.
Apply a small amount of lubricant into the ignition cylinder and insert the key to see if it resolves the issue.

4. Gear Shift Position

Ensure the gear shift lever is firmly in the "Park" position.
If necessary, jiggle the gear shift to confirm it is fully engaged.

5. Battery Check

Use a multimeter to check the battery voltage. A healthy battery should read between 12.4 to 12.7 volts.
If the battery voltage is low, jump-start the vehicle or replace the battery if necessary.

6. Ignition Cylinder Replacement (if needed)

If the ignition cylinder is determined to be faulty, remove it by:
1. Disconnecting the vehicle battery.
2. Removing the plastic cover around the ignition switch.
3. Unscrewing the ignition cylinder retaining screws.
4. Replacing with a new ignition cylinder.
5. Reconnecting the battery and testing the new installation.
