In the single player campaign of Call of Duty: Modern Warfare 2, players will encounter several safes hidden across missions. The method to unlock them usually involves a combination found near the safe, but if you’d rather not search, this guide provides all the codes and explains how to locate each vault yourself. The goal is to help players understand where safes are placed, what to expect inside, and how to use the clues scattered through the levels to unlock them efficiently.

Safe in the mission “El Sin Nombre”
After the ally, Alejandro, frees the player, proceed toward the barbecue area and pick up two throwing knives. These are useful for quietly neutralizing guards without drawing attention. The next step is to move through the open door on the left. A balcony ahead invites a jump to reach the second floor. Upon reaching the top, enter the house, climb the stairs, and enter the first room on the left to reach a room with a pool table.
Advance, eliminate the guard, and continue down the hallway to open the first door on the left, opposite the elevator. Inside is Diego’s apartment. Check the closet near the bed—the safe sits inside. The equipment visible in this room includes a shield and a muted shotgun Lockwood 300. The correct combination for the safe is shown in the photo in the same room.
The vault code for this mission is 02-02-19.
Safe #1 in the “Alone” mission
In the mission titled “Alone,” the first safe rests inside a coffee shop, marked by a distinctive green door. Do not rush to open the door, since a trap lies beyond. Instead, circle the building and enter through a window. Once inside, disarm the loaded shotgun and head upstairs. The door at the end of the hallway must be used to reach the room containing the safe.
Beyond this doorway, a dying man seeks aid, and the player presses forward toward the cafe. Turn left to reach a passage labeled with a sign reading “Entrance is prohibited.”
Approach the safe, interact with it, and use the hints on the calendar to guess the code. Inside this vault you’ll find a throwing knife and a silenced GS .50 pistol.
The code for vault #1 in the mission “Alone” is 10-10-80.
Vault #2 in the “Alone” mission
From the coffee shop, descend the stairs, retreat, and exit through the door by the bar. Step outside quietly and use the blue door near the white car to reach the exterior. The safe is directly ahead, beside the microwave. Opening it yields a throwing knife and a crossbow, and a computer screen in the workshop displays another clue to the combination.
The code for vault #2 in the mission “Alone” is 37-60-80.
After all safes are opened, the achievement “Noble Thief” becomes available. It’s worth noting that any missed vaults can be revisited later in various missions.
