How do you open the trunk of a 2005 Cadillac XLR that wont open by key or release switch?

If the trunk of a 2005 Cadillac XLR won't open with the key or release switch, you can try accessing it through the rear seats. Fold down the rear seats to reach the trunk area, and look for a manual release mechanism or a way to pull the trunk release cable. If this doesn’t work, you may need to consult a professional locksmith or a dealership for further assistance. Additionally, check the car's battery and fuses, as electrical issues can sometimes cause trunk release problems.
