It's ironic that if you talk to the cops about reducing crime one of the things they recommend is using double keyed dead bolts, particularly if there is glass in or next to the door. We had steel security doors made for our old house in Denver, which are nice because they can be locked with the entry door open and are actually somewhat secure. Having a lever deadbolt on those makes no sense as they would be useless.
BTW, the IBC only requires one door like this but it cannot be one that leads to the garage.
