Okay so one day I go to lock my car, I do it manually with the key, and I turn it both ways and nothing happens. I go to the other side and try that door and it locks and the alarm goes on b/c the red light is blinking on the driver's side. So then yesterday I go to the routine lock the car and I try it from the passenger side and try it and just like the other side it has no effect. The doors lock and unlock okay when you are sitting in the car but when you try the key nothing happens. It's so weird that all of a sudden within a few weeks of each other they both don't work. Do you guys think its the door handle or something inside the door came apart? Also would it be cheaper just to put an alarm in or try and get it fixed? Thanks for the help.
