As you investigate the cold storage at the Clarkson Food Delivery Services building in Deadly Premonition 2, you will need to find a key to the elevator in order to get down to the lower levels. To do this, you will need to do a lot of trolley moving.
If you turn around from the elevator door, on your right you will notice a trolley that you can you push. This will give you access to a warren of shelves, with lots more trolleys to move in order to make your way through. Push the first trolley as far as it will go, then move to the trolley you can see on the right.
Push that trolley, then turn left, and push the next trolley straight forward as well. There will now be a trolley directly to your right. Push this one two steps forward, then squeeze between it and the next trolley, and push it all the way back. Grab the newly exposed trolley and drag it backward, the crouch to get through the gap in the shelves. Turn left and pull the next trolley back as far as you can, then let go and push it towards the wall.
In the next area, you will see a break room with a sleeping staff member in it, and he will have the key to the elevator. To quickly make your way back, just grab the trolley near the shelves to the left of the door as you leave, crouch under the shelves, and then walk along the wall to get back to the elevator.
