Evening gents, when I lock the old girl she locks then unlocks! I have changed the fob battery and am also changed all door contacts but it hasn't changed anything! Any help? Cheers!

Evening guys, I'm not sure whether I'm aloud to ask for help and advice or where the post needs to go! When i lock my defender it locks and 2 seconds later it unlocks. On occasion the hazards start after 30 seconds or so. Any one had this problem? Also I have a air horn instead of a beep beep...

Evening all, I'm new to the group, driving a defender 90 td5 and a old 109 that is currently in storage awaiting restoring!
