I have a 1997 F150 Lariat. I had the Positive Battery cable & battery replaced today. When I got my truck back I noticed it did not make a noise when I unlocked my door with the Fob. I researched how to reset the alarm and did what it said. The red indicator flashes and the doors lock & unlock with the Fob, but still no sound like before when I knew my alarm was set. Any suggestions. I made sure the doors and hood were closed.
