* Steering Wheel Lock: This is the most frequent cause. The steering wheel is mechanically locked to prevent theft, and if the steering wheel isn't perfectly straight, the key won't release. Try gently jiggling the steering wheel while turning the key.
* Shift Lever Not in Park (Automatic) or Neutral (Manual): The car's safety mechanisms prevent the key from being removed unless the transmission is in park (automatic) or neutral (manual). Double-check the gear selector.
* Faulty Ignition Switch: The ignition switch itself could be malfunctioning. This is more likely if you've recently had issues with starting the vehicle or if the key feels loose in the ignition.
* Broken or Worn Key: A damaged or worn key might not fully engage the ignition cylinder, preventing its release.
* Low Battery: A weak battery can sometimes interfere with the electrical signals that release the ignition lock.
* Stuck or Damaged Ignition Cylinder: The cylinder itself might be jammed with debris, or it could be worn down and damaged.
* Aftermarket Accessories: Sometimes aftermarket alarms or other electrical accessories can interfere with the ignition system.
What to do:
1. Try the obvious first: Make absolutely sure the gear selector is in park (automatic) or neutral (manual). Gently jiggle the steering wheel while trying to remove the key.
2. Check the battery: If the battery is weak, jump-starting the vehicle might resolve the issue.
3. Try a spare key: If you have a spare key, try using that. If the spare works, your original key is likely damaged.
4. Use some lubricant (with caution): A small amount of graphite lubricant *sprayed into the keyhole* (not inside the ignition cylinder itself) might help if there's a minor sticking issue. Do not use WD-40; it can attract dirt and gum up the mechanism.
5. Call a locksmith: If none of the above works, a locksmith is your best bet. They have specialized tools and expertise to deal with stuck keys and ignition problems. They can often resolve the issue without damaging your car's ignition.
6. Towing: In some cases, especially if the ignition cylinder is severely damaged, you might need to have your vehicle towed to a mechanic.
Important Note: Avoid forcing the key. This could damage the ignition cylinder, leading to more expensive repairs.
