Call of Duty: Modern Warfare 2 features a number of secret Safes hidden in some of the game’s levels. Finding and opening them will give you both additional equipment as well as an Achievement or Trophy. Here are all of the Safe locations and the codes you need to open them to unlock the Gentleman Thief Achievement/Trophy in Call of Duty: Modern Warfare 2.

Modern Warfare 2 First Safe Location and Code – Mission 11: El Sin Nombre

  • Code: 02-02-19
  • Rewards: Plate Carrier and Lockwood 300 Shotgun

The first Safe is located upstairs in the mansion inside Diego’s bedroom. To get there, after you exit the elevator and wear the mask, head straight, then go to the left, passing through a gate and into the backyard. Climb the balcony at the end of the area to get upstairs. Walk straight again through the corridor, then take the corridor on the far left. Diego’s bedroom is the one on the left. Inside, open the sliding doors to access the closet, and you should find the Safe embedded in the wall.

Second Safe – Mission 13: Alone

  • Code: 10-10-80
  • Rewards: Throwing Knife and .980 Handgun

You can find two Safes in Mission 13. Let’s look for the first one.

After you disarmed the shotgun door trap and went past the dying, crawling man, instead of dropping down the broken balcony railings, head to your left and unlock the locked door with a Pry Tool; the material (Binding and Metal) can be found in the rooms before this part if you need them. Just behind the locked door is the second Safe.

Third Safe – Mission 13: Alone

  • Code: 37-60-80
  • Rewards: Crossbow

Now, after opening the first Safe, it’s time to descend the balcony. Go through the door on your left to exit the building, and then look for a blue door with El Maistro written above it near a white car. Enter the door, then look for a small office room where the Safe is located, just beside the small fridge and microwave.
