You can access another vechicle's battery and hook up jumper cables to their battery. On your car, ground battery to engine and attach red to wire on alternator. Do this just long enough to use electric trunk pop then disconnect. If your electronic trunk opener doesn't work too, call a locksmith.
thank you ;-)
