1. Verify the Obvious:
* Key Condition: Is the key itself damaged, bent, or worn? Try a spare key if you have one. A damaged key is a common cause.
* Key Position: Make absolutely certain the key isn't partially turned. Sometimes a slight bump can leave it in a position that prevents further turning.
* Steering Wheel Lock: While you say you've tried manipulating the steering wheel, ensure it's completely free and not binding in any way. Gentle rocking back and forth may help.
2. Addressing the Ignition Switch Mechanism:
* Lubrication: This is a common solution, but use caution. Do NOT use WD-40 or other penetrating oils. They attract dirt and can gum up the mechanism over time. Instead, use a very small amount of graphite lubricant (available at auto parts stores) applied carefully to the ignition cylinder. Work the key gently in the ignition to distribute it. *Too much lubricant can cause more problems*.
* Ignition Cylinder Tapping: Some people find carefully tapping the ignition cylinder (with a small hammer or the handle of a screwdriver – NEVER strike directly with the metal end) can help dislodge a stuck tumblers within the lock mechanism. This is a high-risk approach, and could potentially damage the cylinder, requiring replacement.
* External Forces: Avoid applying excessive force to the key or the ignition switch itself. You risk damaging the ignition cylinder, which is an expensive repair.
3. If the Above Fail:
* Professional Assistance: This is the best option. A locksmith experienced with automotive ignition systems is equipped to handle this situation safely and effectively. They have tools to gently remove the cylinder and address the mechanical issue without causing further damage.
* Towing: If the vehicle cannot be started, it might need to be towed to a mechanic or repair shop.
Important Considerations:
* Damage to the Ignition: Forcing the ignition switch can permanently damage it, leading to a much more costly repair.
* Security System Interference: If the vehicle has an aftermarket anti-theft system or alarm, this might be interfering with the ignition. Try disabling it temporarily if you are familiar with the system.
In summary: Start with the simple checks (key, steering wheel), then proceed cautiously with lubrication. If those steps fail, it's time to call a professional locksmith or mechanic before causing more harm. Remember, prevention is key – regular key maintenance and periodic lubrication (with graphite) can help prevent future issues.
