The driver side automatic door mechanism broke. This happened when the door was shut and locked. I realized it was broke when the automatic key-chain door opener wouldn't work, the key would not unlock it, and the button inside the car would no longer unlock the door. It was shut and stuck locked. A total bitch. I had to get this fixed and it costs a lot of money and a lot of time to get a door open that has been locked shut. Five months later the same problem happens to the passenger side door!
