2007 XK Electrical Problems--ignition maybe?

Trying to help my father-in-law who owns an XK that constantly kills batteries. The car seems to always have something electrical running. I have sat in the car with the key fob nowhere near the vehicle and I can hear something electrical running in the area of the steering column and radio area. The radio is also able to be turned on and off when the car is not running. The car has push button start. Is it possible that the ignition is in the aux position all the time? Has anyone had or herd of such a problem? Any info is greatly appreciated.

Hi Scott I’ve moved this to the correct forum, hopefully someone will have an idea what your cars problem is.
