'Following Orders' lockbox code location in Modern Warfare 4

The Call of Duty: Modern Warfare 4 lockbox code in "Following Orders" is necessary if you want to open the locked container in the small side bedroom in the house of the first family you must interrogate. This mission doesn't hold back, as you're playing as a North Korean soldier searching for a defector, and as a result, you must threaten innocent civilians. This lockbox is the only locked container to find in the mission, however, and if you obtain what is within, it makes getting the information out of the husband much easier.
