Door ajar switch problem more then likely or wiring issue . The BCM - body control module won't turn off interior light , let door lock because it think's the door is open . The door ajar switch is a input to the BCM .

The first thing would be to have it checked for DTC'S - diagnostic trouble codes . Also check with an enhanced scan tool to see if the BCM shows ajar switch data (open or closed ? Do you know about body electronics ?

The horn chirp can be disable by pressing the lock and unlock buttons simultaneously until the hazard lights flash, and no enable press the lock and unlock until the horn chirp.
To reprogram (enter new ID) key fob (keyless remote controller) follow the steps.
1. Close all doors and lock all doors
2. Insert and remove the key from the ignition key cylinder more than six times within 10 seconds. (The hazard warning lamp will then flash.) NOTE: Key should be withdrawn from ignition key cylinder completely each time.
NOTE: Do not rush the insertion/removal key cycling process. The side marker/tail/license lamps and interior illumination will flash twice when this step is accurately completed.

Look in your manuel, there are steps to change the Key less remote setting to customize it the way you'ld like the car Key less system to work.
Good luck and hope this helps, if your still having problem. Just drive the Dodge dealer and ask the Service adviser to help you out, he or she would be more then happy to reprogram the key less system for you.

There is a switch either in or on the driver door that turns on the interior lights and tells the module the door is open and the key is still in the ignition, this sounds the alarm, check all the doors and make sure they turn the interior lights on and off when the doors are opened and closed.

If remote locks and unlocks driver door but does not unlock passenger doors,then follow the advice above:
Get in the car using the key to unlock the doors. From the passenger side lock and unlock your doors using the button on the passenger door. Get out and the remote should now unlock all the doors with 2 presses.
Worked perfectly for me after several other suggestions (and dealer) failed.
