I lock my doors with the remote, horn sounds-alarm sets. I unlock the doors with the remote (within 1-2 minutes) and the doors unlock and the alarm is deactivated. If it sits any longer than a few minutes the remote will still unlock the doors but the alarm will go off and will have to hit unlock on the remote once the door is open (either door) to shut it off. Also, the remote won't open the trunk until after the door has been open as well. If I hit the trunk button on the remote before I unlock and open the door the trunk will open as soon as I open the door. I have retrained the remote and no changes. This is driving me nuts....
