I recently ripped the factory stereo out and installed a new cd player in my 2000 Plymout Neon. The radio works fine. Now I have a problem with the locks. When I hit lock or unlock on the key chain the only thing it does is turns on and off the alarm but the locks never move. Also when I hit the lock / unlock switch in the car both passenger and driver side nothing happens but I do hear some sort of clicking in the dash area around where the heat / AC controls and radio are. As of now I have to manually use the key to lock / unlock the door from the outside and use the manual switch on each door to lock or unlock them from the inside.
