As Blast said, the shove knife is for unlocking simple door locks. The shove knife is basically the end of a slim-jim car door opener that can be used in about 10,000+ ways. Most common is to open a door similar to how you see a credit card used in the movies (except this works better and doesn't break).
Elevator key's are for opening the outer doors of an elevator to gain access to the shaft/car. If you look at an outer door for an elevator you will see a small hole about 1/2" in diameter. The flat part of the key is inserted into this hole and drops down once clear the door. Rotating the key towards the outside of the elevator pushes a release level allowing the door to be opened.
Recently we had a stuck elevator call where a janitor, trying to be helpful, tried to force some large door wedges into the gap between the doors in an attempt to free the women struck inside. Once we got there, the release mechanism was damaged to the point where we basically had to break the door and release mechanism to get the door opened... needless to say the building's owner was less then thrilled with the $8000 bill to repair the door, he was happy with us once I explained what happened (not so much with the cleaning crew though).
I was just thinking the other night about what I carry in my pockets and the evolution both my off-duty EDC and my on-duty EDC has taken over the years as well as how the contents of my tunrouts have changed over the years.
