When you get to the location of the van it will be locked. Head to the police station and get the NOOSE outfits. But note that as soon as you reach the exit, the agents will recognize you and start shooting, so make sure you have some snacks and armor.

So if you've hacked one then make sure you remember the pattern on the first one, as all the other ones in the vault will have the same pattern. However, since we are not planning on getting into any combat situations, this mission is not necessary.Getting the vault keycards is the easiest prep mission. DO NOT take the elevator. Not only that, but there will be a number of agents all across the race track. A guard will come by the door and then he will return back to the left hand side of the door.

After you reach the requisite floor, take your phone out and find the hacking device using the signal strength bar, the same way you did when in N.O.O.S.E headquarters.This is an optional general prep mission, but it is one of the most important prep missions, especially for the Big Con approach. The other requires you to get it off of a dead valet's body while you impersonate a Coroner officer.You do not need to worry about choosing the best gunman for this approach since you won't be getting into combat situations. Instead, swipe your keycard on the staircase door and head through the staircase all the way up to the staff lobby area.If you get a mission where you need to go to the FIB building, you will first have to go kill some agents and get the FIB agent pass so you can impersonate that agent. Once Lester has identified the target, you need to find and search for the keycard on them.

Note that you can do all these heist prep missions either solo or with your friends. You need to take them all out (the cops and the criminals) and get the drills. They will be passed out and once you search for the keycard you'll discover it's not actually on them.
You can go directly to the prison in your own vehicle and head to the tower to get the keycard.

You can also do the prep missions in either public or solo sessions.Once inside the tunnel keep driving until you're roughly in the middle of it and wait for your wanted level to go away. Hug the wall and stay clear of the cone of visions of these security cams.You do not need your driver either, since you won't be using the getaway vehicle for this approach. You will come across two keypads which need to be activated by you and your friend simultaneously.
Just make sure when you are going in killing everyone, not to accidentally blow up the target car!
