2012 Range Rover Alarm issue

Hi all have a issue with alarm. When I lock the RR after a couple of minutes the alarm sounds briefly then the clock and date reset. It's the same when I unlock the RR after a short period or several days the alarm sounds and the clock and date reset. I've checked all the fuses and changed the battery all to no avail can anyone help.
