I own a 2002 dodge stratus, today when I got home I was getting out and locking my car, except my doors wouldn't lock. My button wouldn't lock or unlock them with the door open. I do this everyday and there hasn't been a problem before. My doors will lock and unlock if I sit in my car with the driver's door shut. It recently started getting cold, not sure if that has to do with it.
So if this is a feature to keep me from getting locked out, and it never worked before. Why all of a sudden in the three years i've owned it just now starting to work?
