Concerning the Auto door locks with the remote. Previously whenever I press the remote lock the horn would beep as the doors would lock. All of sudden that has stopped and when I press the remote door lock the doors lock but the horn does not beep. Also the battery died thsi morning, but was almost 3 years old, so I replaced it which corrected the issue with the vehicle not starting, but when I presse the romote door lock the horn still does not peep. Is this a problem that has not surfaced yet?
