If you’re struggling to find the Diego’s keycard in MW2, you’ve come to the right place. The campaign for Call of Duty: Modern Warfare 2 is currently playable. Fans have already praised it as an entertaining and interesting cinematic experience. Its epic, action-packed plot pits Task Force 141 against Iranian military and a Mexican drug cartel while spanning multiple continents.
Stealth missions are a feature of Call of Duty campaigns that fans especially enjoy. And Modern Warfare II has a ton of those. There’s just something really gratifying about moving covertly, taking down guards with caution, and avoiding detection.

Players control John “Soap” MacTavish in El Sin Nombre as he infiltrates a cartel home. Yet unlike the linear run-and-gun experience that CoD players are used to, the level is not linear. You and Alejandro are able to get entrance to the mansion’s penthouse after being interrogated by cartel members Diego and Valeria.
You have two options for how to tackle the mission at this point. Either use Diego’s keycard to access the elevator and travel to the third story, or discover a route to the roof. If you decide to use a keycard, follow these instructions.
Use the elevator or the roof by finding Diego’s keycard. You’ll need to search the mansion for the keycard if you decide to do that. But, its precise location is unknown, and you must go in search of it. This means that if you’re wondering “Where is Diego’s keycard in Call of Duty: Modern Warfare 2?,” keep reading because we’ll explain how to do so.
How to get Diego’s keycard?
It is not easy to locate Diego’s keycard. As you navigate the estate and try not to alert the cartel’s guards, it calls for patience and prudence. After exiting the elevator, move forward and then turn left. After that, continue straight until you come to a staircase. It is being blocked by a guard.

Wait for the security guard to move or exit the building, turn right, and ascend the stairs to the balcony. Gather the bottle when you get to the top of the steps. This can serve as a diversion.
Enter the room with the pool table through the first door. More bottles can be found here, along with throwing knives.
Be careful around the guard on the left as you exit this chamber. Kill or draw the guard’s attention away from the entrance that he is blocking to the chamber where Diego and his keycard are.

Once the guard barring the entrance has been removed, carefully enter. You’ll come across another guard. Diego is standing at the opposite end of the space. Murder both of them.
Diego was standing in front of the altar, which holds his keycard.

You can use the keycard you now possess to start the elevator and ascend to the penthouse.
