I don't have an answer I need one fast please...
Use metal key insert. If trunk lock doesn't work spray a bit WD40 oil up key access slot and persist. It will work after you wiggle it around and free it. I had same with flat battery. Locked out! Lock goes stiff with lack of use.
you can consult the locksmith to open it.
the key slot is in trunk
