This page is a walkthrough for The Doomsday Heist Preparation Mission, Keycards. It’ll navigate you through the necessary steps to successfully acquiring the Riot Van.
Steal a riot van that contains keycards to the hangers at Los Santos International Airport.
Go to Alhambea Drive / Steal the Riot Van
Once you’ve started up the mission, take any car and follow the waypoint to Alhambea Drive which is where a riot van is currently in use. Upon arrival, take out the Police whilst they’re distracted, then jump into the Riot Van and make a quick escape.
You’ll now need to do some sneaky driving to lose the cops or if you’re having no luck, then call up Lester and choose the “Remove the wanted level”. Finally, deliver the Riot Van to your Facility to bring this mission to a close.
