Bringing this back....
This happened to me yesterday while we were at a cookout. The doors locked, then I heard a loud buzzing/clicking noise coming from the passenger side of the cars. Now the doors won't unlock. I check the fuses related to the locks and replaced fuse #57 which was blown and the central locking button will still not work and I still cannot open any of the doors except for the driver's side.
What really sucked was trying to get our 7 month old and his car seat in the car and get him home and out of the car. We finally had to climb in the back through the driver's side and pass him through the dam window.
I'm headed to the dealership this evening and will update here with the outcome. I'm sure this won't be cheap since my car is out of warranty.
