Your gonna have to call someone like locksmith, AAA, or any roadside service you have access to. You can try the old wire hanger through the top of the door trick but it takes awhile and you have to be very patient. I had to do that once, I used a wire hanger to reach into the car and a flathead screw driver to pry the door open a little. About an hour later we found the spare key after I got the door opened lmao, now there's some nice scratches by the door from the screw driver.
