To open the trunk of a 2005 Chevrolet Cobalt without a key, you can try using the manual release lever inside the car, typically located near the driver's seat.

As a last resort, contacting a locksmith or a dealership for assistance may be necessary.

If all else fails, you may need to jump-start the battery to regain power.
