For the Diamond Casino Heist, acquiring a Level 2 Security Pass is practically mandatory, it allows you to bypass many locked doors without hacking. This guide details the two different mission types you might encounter to obtain this pass: the Croupier/Party method and the Coroner method. We also cover some frequently asked questions regarding security passes.
For the first type of mission you will be instructed to go to a pool party. Once you reach the party, a suspicion bar, at the bottom right corner of your screen, will become visible. It will gradually increase if you become more noticeable and attract attention, however, you need to blend in and make sure it doesn't rise. You can do different activities such as drinking and dancing to keep the suspicion bar low. Once Lester has identified the target, you need to find and search for the keycard on them. They will be passed out and once you search for the keycard you'll discover it's not actually on them. However, it should be laying around somewhere in the area. You need to search for the keycard around the area.
Your suspicion will still increase slightly, but the best way to keep it low is to go to your interaction menu and keep your action to dance, and turn it on permanently. This way you can walk around and search for the card while making sure the suspicion bar is not increasing.
If you get a coroner mission, then you will need to go to the church and steal a hearse. Once you do so the cops will instantly be on you. Once you lose them, head to the coroner's office. You will automatically equip the coroner officer's clothes. Enter the office and proceed to the morgue. Avoid the cops' cones of visions inside the office as much as you can. Once you reach the morgue, search valet's body and get the keycard. Just ensure that no one is watching you while you do so. After that head back the same way you came in, while avoiding the cops. Leave the area to successfully complete the prep mission.
What is the difference between the Level 1 and Level 2 security passes?
Level 1 is actually useless. In addition, Level 2 cards allow you to enter through all the doors without the need to hack them. With Level 1, you will need to hack doors to get through them. It makes your heist much easier especially if you are doing silent & sneaky approach.
Do you select the Security Pass mission or trigger it?
It is on the heist prep board at the bottom right corner where it says "Security Pass". Underneath that, you can switch to either the level 1 pass mission or level two pass mission. When you start the mission read the prompt that will pop up asking for a confirmation to start the mission for a level 2 security pass.
How can I search for the Croupier?
Once you head into the party, wait for Lester to send you a picture of the Croupier. Check the picture in your phone's messages and then look for an identical person in the party. The Croupier will likely be on the ground extremely drunk. So try to look for passed out people on the ground. As you get closer to the Croupier, he/she will be identified (you will see an arrow on top of them) and you will get the option to search.
After that, if the card is not on them, you need to search for it in the surrounding area. Initially it will not be marked with an arrow so just look for a highlighted/glowing object. Once you get closer to it, you will identify it and just grab it.
Securing the Level 2 Security Pass will greatly simplify your movement within the casino during the finale of your approach.
