* Steering Wheel Lock: The steering wheel is locked. Try gently jiggling the steering wheel while turning the key. If the steering wheel is slightly turned, this can prevent the key from turning.
* Broken or Worn Ignition Switch: This is a common problem in older cars. The switch itself might be failing, preventing the key from engaging properly. This often requires replacement.
* Damaged Key: The key itself might be worn, broken, or improperly cut. Try a spare key if you have one.
* Shift Lever Not in Park (Automatic): Ensure the gear selector is firmly in the "Park" position. If it's not, the car's safety mechanism will prevent the key from turning. (For manuals, ensure it's in neutral).
* Faulty Ignition Cylinder: The ignition cylinder itself might be damaged or worn, preventing the key from turning. This often requires replacement.
* Low Battery: A very low battery can sometimes interfere with the ignition system. Try jump-starting the car.
* Security System: If your Skylark has an aftermarket or factory alarm system, it might be activated, preventing the key from turning. Check the alarm system's indicators.
* Something Stuck in the Ignition: Debris, such as broken key pieces or a foreign object, might be lodged in the ignition cylinder.
Troubleshooting Steps:
1. Try the spare key: This will quickly tell you if the problem is with the key or the ignition system.
2. Check the steering wheel: Gently jiggle it while trying to turn the key.
3. Check the gear selector: Make absolutely sure it's in Park (or Neutral).
4. Check the battery: A weak battery can cause strange electrical issues.
5. Look for obstructions: Carefully inspect the ignition keyhole for any foreign objects.
If none of these solves the problem, you'll likely need professional help. A locksmith or mechanic specializing in older vehicles can diagnose and repair the issue. They'll have the tools and experience to determine if the problem is with the key, the ignition cylinder, the ignition switch, or another component of the ignition system.
