BC Toolbox Location in Modern Warfare 2 DMZ

You will first need to travel to Al Malik Airport, which is located to the southeast of Al-Mazrah, in order to locate the MW2 DMZ BC Toolbox and proceed with the use of the key that corresponds to it.
After arriving at the location, proceed to the north door of the enormous central airport building and enter the facility.
You should be able to see a baggage conveyor belt on the left side of the building once you have entered the building. You will need to make your way through the small gaps that the luggage moves through.
However, there is a possibility that there are a few adversaries lurking around here, so you should make sure that you are aware of the potential threat.
You should be able to see a tiny toolbox that is locked once you have entered the building and have jumped over the interior conveyor belt.
You may open it up using the key to your MW2 DMZ BC Toolbox, and then you can enjoy the stuff that is contained within it.
When you leave the airport, there is a good probability that you will come across a large number of artificial intelligence adversaries, even if you did not come across them when you were entering the airport.
Despite the fact that they might not be the most dangerous on their own, they certainly have strength in numbers and have the ability to quickly take you down if you are not careful.
