I am having an issue where the rear driver side door will not lock when I use the key fob or when I use the lock button on the front doors. This prevents the alarm from activating unless I manually lock the door. This has been going on for a month or so but hasn't been a big deal since the door is rarely used. However, the same issue is happening with the driver side front door. I have replaced the battery for the fob and that didn't fix the issue. Has anyone else run into this issue? Any suggestions would be greatly appreciated.
