Help with Locks

This is embarrassing, but I can't get in my car. My passenger side door handle has been broken for sometime now and my back doors are locked without a keyhole. The driver's side front door is the only real option I think I have. It feels as though maybe the key is not actually unlocking the door. I'm not for sure though. I can't even get in the vehicle to take the door panel off or anything to check it out. How can I get inside my vehicle? Please help me! I need to be able to drive my vehicle!
Thanks!
