Easy, its not hard. First you do your pre work, which worker holds the safe key, what day is banking done on,who is on the alarm call out list and how far away they live from target. you break in via a canteen window or roof, somewhere that the person attending site to reactivate the alarm can't see the source as believe me they have tonnes of false alarm call outs. once they are on site they can he forced to deactivated the alarm and if carrying safe key can open main safe or be held hostage until you have finished cutting through the safe door. you have to use expanding foam in all firearms to stop them going off. There's a few other issues but i can't be arsed to write them all down using my phone .
