i've had the same problem, try this. Go outside the driver side, pull on the handle like you're opening the car a couple times, then use your palm and push the handle in with some force, while doing this unlock it at the same time with your key or someone on the inside hit the switch. If this works, then you need to get a new latch. (when you open the door, its the piece on the side of the door that locks to your door jam.)
