FNG here, need help with an alarm problem on a 2009 F250 Super Duty. I unlock the doors with key fob, get in, close door and turn on truck. As I've always have, I take off and lock doors with power lock switch. The alarm activates. Everything operates normally until I turn off the engine. Alarm sounds. I've recently installed a new battery. Before the battery switch I've never had this problem. Any help would be greatly appreciated.
