After you have been introduced to Carlos and you arrive at the Subway carts with all the survivors, you’re told to go topside to restore the power to the Subway lines. Once you reach the streets you are allowed to explore a large portion of Downtown. Much of it is immediately open but some of it is locked behind chains. Once you’ve got the Bolt Cutters, you can explore the locked areas and grab yourself some special loot, such as the shotgun.
Before you can reach the Bolt Cutters, you need to put out the fire in the alley. You need to find a fire hose near the Subway Control Room and then use it on the Fire Hydrant in the alley to clear the flames so Jill can continue. Directly after the fire is cleared from the alley you will reach a Repair Shop. As soon as you enter the Repair Shop you will see a pair of Bolt Cutters in front of you. Simply walk up to the locker, it’s not locked, and interact with the Bolt Cutters to pick them up and take them with you.
