You need to get the door open - a mobile car lock specialist will help ££.
Your interior door panel will very probably have a few screws very low down in the sill line - check it out on the passenger door. Without first removing these screws it will be impossible to push the panel upwards (the usual method to get it off) and you can't get the screws out with the door closed.
Good luck...
