1. Check for Spare Keys: The most obvious solution is to see if you have a spare key hidden somewhere – under a floormat, with a neighbor, etc.
2. Unlocking the Trunk Manually (If Possible): Some models might have a way to access the trunk from inside the car (e.g., a lever or button). Unfortunately, the 2007 Malibu usually doesn't have a direct interior trunk release *unless* your car has a power trunk release button; check your armrest or console. This is unlikely if your keys are locked inside.
3. Using a Spare Key FOB (if applicable): If you have a spare key fob with remote unlocking, try unlocking the car. Sometimes, even if you don't have the physical key, a working remote will unlock the trunk.
4. Professional Locksmith: This is the most reliable solution. A locksmith has specialized tools to unlock your car without causing damage. They can usually get into your vehicle quickly and efficiently. This is usually the best option to avoid potentially damaging your car yourself.
5. Roadside Assistance: If you have roadside assistance coverage through your insurance or a membership like AAA, they can send a locksmith or tow truck.
6. Dealer: As a last resort, you can contact a Chevrolet dealership. They might be able to help, but it's likely to be the most expensive option.
Important Note: Avoid attempting to force the trunk open yourself. This can easily damage the locking mechanism or other parts of your car, leading to costly repairs. A locksmith will know how to get in without causing such damage.
