1. Verify Park:
* Shift Lever: Make absolutely sure the shift lever is firmly in the Park position. Sometimes it might *feel* like it's in Park, but isn't quite engaged. Try gently rocking the car back and forth while the lever is in Park to make sure it's seated correctly.
* Shift Interlock: The shift interlock mechanism prevents the key from turning unless the car is in Park. This is the most common cause. If it's faulty, the key won't turn, even if the lever *feels* like it's in Park.
2. Steering Wheel Lock:
* Turn the Steering Wheel: Try gently turning the steering wheel back and forth a small amount. Sometimes the steering wheel lock engages, preventing the key from turning. A slight turn can disengage the lock.
3. Ignition Switch:
* Worn or Damaged Switch: The ignition switch itself might be worn, damaged, or failing. This is a more serious mechanical issue and will likely require professional repair or replacement.
* Loose Connections: There could be loose connections to the ignition switch. This is less likely but possible.
4. Electrical Issues:
* Battery: A weak battery can sometimes affect the ignition system. Check the battery voltage.
* Fuses/Relays: Check the fuses and relays related to the ignition system. Your owner's manual will show you where they are located and how to check them.
* Wiring Problems: Damaged or corroded wiring can interfere with the ignition system. This is difficult to troubleshoot without a multimeter and some electrical knowledge.
5. Other Potential Problems:
* Anti-theft System: If your Stratus has an aftermarket anti-theft system, it may be activated and preventing the ignition from turning.
* Broken Key: While less likely, the key itself may be damaged or worn.
What to do:
1. Start with the simplest: Double-check the Park position and steering wheel.
2. Check the battery: A weak battery can cause strange electrical problems.
3. Consult your owner's manual: It will provide diagrams of the fuse box and relay locations, and other helpful information.
4. If none of the above works: It's time to call a qualified mechanic or towing service. Trying to force the key could cause further damage to the ignition switch. This is likely a mechanical issue requiring professional attention, and safety should be your priority.
Don't force the key. Forcing it will likely worsen the problem and possibly damage the ignition switch, leading to more expensive repairs.
