Remote Locks Causes Horn to Beep 3 Times?
For the last couple days every time I press Lock or Unlock, the horn sounds three times. The manual says if one of your doors is open the alarm may sound several times to let you know the security system is not armed. I have checked all the doors and they are definitly shut. When I first got the truck I changed it to the RFM that makes the horn beep once only when you lock the doors. It has workded fine until just recently.
