I have a 2012 civic lx , the remote unlocks and locks the door and the key works in the ignition but will not work manually to lock or unlock the door. if the battery dies I need to have the key work so I don't get stranded somewhere. Am I doing something wrong or is there a setting that has not been enabled for the mechanical key to work in the door lock? thanks for any help. The guy I purchased it from has no idea and no help. He said he never used the regular key except in the ignition. Maybe this issue has been brought up before but I could not find any similar posts.
