* Use your key: The simplest method is to use your key in the driver's side door lock. This should unlock the door. If your key is broken or jammed, you'll need a locksmith.
* Unlocking from the passenger side (if applicable): If your passenger side door is also lockable from the outside with a key, try that door.
* Check for a hidden key: Some cars have a hidden key release under the dashboard or glove box. However, the 2000 Sunfire is not particularly known for having this feature. Check your owner's manual to be sure.
* Unlocking from inside (if access is possible): If a window is slightly open or cracked, you might be able to reach inside to use the manual interior door handle. If it's slightly open, you may even be able to use a coat hanger to reach the unlock mechanism. This requires some dexterity.
* Call a locksmith: If all else fails, a locksmith is equipped with tools to open your car without damaging it. This is the safest and most reliable option if you can't open the door yourself.
Important Note: Avoid forcing the door open, as you could damage the locking mechanism or the door itself.
