All MW4 Key Codes & Locations

There are 13 Key Codes to solve in the Modern Warfare 4 campaign, spread across four of the main missions, though the vast majority are in the Stranded mission.

The Stranded mission in Modern Warfare 4 has eight Key Codes to crack, hiding some decent loot behind them, and are, in many cases, the easiest to find as there are precise coordinates available to track on the map.

The other missions, meanwhile, can vary, so keep your eyes peeled for any locked doors, safes, or similar.

While you can miss these rewards, you can go back at any time to grab what you missed the first time around, which is particularly useful in the Stranded mission, where progress is saved separately from your main playthrough.

The table below details the mission where each Key Code can be input, the solution, and, where possible, coordinates.
