When wife locks driver's door, rear doors stopped automatically locking about a week ago.

When front doors & trunk lock by key, opening unlocked rear door sets off alarm.

When front & rear doors are locked & rear door lock buttons are engaged manually, all doors remain locked and when driver's door is then unlocked with the key ALL doors & trunk automatically unlock normally.

Anyone have a clue as to the problem and the fix?
