my Toyota Corolla E170 (2013-2019) key won’t turn in the ignition, what should I do

Solution

1. Preparation

• Tools Required: Flathead screwdriver, lubricant spray, replacement key (if needed).
• Ensure the vehicle is in "Park" or "Neutral" mode for automatic transmission.
• Disconnect the battery before working on electrical components.

2. Inspect and Lubricate Ignition Cylinder

• Remove any debris around the ignition keyhole using a flathead screwdriver.
• Apply a small amount of graphite lubricant into the ignition lock cylinder. Avoid using oil-based lubricants as they can attract dirt.
• Insert the key and attempt to turn it after allowing the lubricant to penetrate for a few minutes.

3. Check Steering Column Lock

• If the steering wheel is locked, gently turn the steering wheel to the left and right while attempting to turn the ignition key.
• If successful, the ignition will turn, and you can start the vehicle.

4. Replace Ignition Lock Cylinder (if necessary)

• If the key still does not turn, you may need to replace the ignition lock cylinder.
• Tools Required: Socket set, screwdriver set.
• Remove the plastic cover from the steering column using a screwdriver.
• Locate the ignition lock cylinder retaining screw and remove it.
• Disconnect the wiring harness from the ignition lock cylinder.
• Replace it with a new ignition lock cylinder, ensuring it aligns with the steering mechanism.
• Reassemble the steering column cover and reconnect the battery.
