All door handles not working?

Exterior door pulls on 97 328i all broken. My negligence, as they went one at a time and I didn't repair, but now I can't get in. Can you access this model through the trunk?

For what it's worth actually have a 328i, not xi. I can't get into the car because one by one all of the exteriors door pulls have broken, and I neglected to do anything about it. The interior pulls all work still. Can I access the interior of the car any other way?

Through the trunk perhaps? And what do you think the approximate cost of repairing the door handles will be?
