* Steering Wheel Lock: The most common cause. The steering wheel is likely locked, preventing the key from being released. Try gently jiggling the steering wheel from side to side while trying to remove the key. Sometimes, a slight turn of the wheel is all it takes to disengage the lock.
* Shift Lever Not in Park (Automatic Transmission): Make absolutely sure the gear selector is firmly in Park (P). A slightly out-of-position selector can prevent key removal.
* Faulty Ignition Switch: The ignition switch itself might be malfunctioning. This is less common than the steering lock issue, but possible. A damaged switch can prevent the key's release mechanism from working properly.
* Broken Key: Although the car turns over, a broken or damaged key might be jamming the mechanism. Inspect the key carefully for any bends or breaks.
* Worn Key: Over time, keys can wear down and no longer fully engage the ignition tumblers. This might cause the key to turn but not release properly.
What to Try:
1. Steering Wheel Jiggling: Try this first. Gentle, back-and-forth movement of the steering wheel.
2. Shift Lever Check: Absolutely confirm the shifter is fully in Park. Try gently moving it back and forth in the P position.
3. Key Lubrication (Use with Caution): A very small amount of graphite lubricant (like powdered graphite, *not* WD-40 or oil) *might* help if the key is sticking due to friction. Apply it sparingly and only to the key's teeth, and avoid getting it into the ignition cylinder.
4. Different Key (If Available): Try using a spare key if you have one. This can confirm if the issue is with the key or the ignition itself.
If none of these work:
You'll likely need professional help. A locksmith or a mechanic specializing in automotive electrical systems will have the tools and expertise to diagnose and fix the problem. They might need to replace the ignition switch, which can be a moderately involved repair. Do not attempt to force the key, as this could damage the ignition cylinder further.
