I went to get in my 05 STS V8 4.6L today and when i pulled the handle the door would not open. When i pulled the handle i heard the beep, light on the door lit and the actuators sounded like they moved but door still remained locked. I tried to unlock with fob but still would not open. I had to go to the passenger side and open the driver's door from inside the car. All the other doors opened fine. Can anyone share their insights on the matter?
