MW3 Buy Stronghold Keycards

You can purchase Stronghold Keycards for 2,000 Essence at Buy Stations. This is the easiest and quickest way of acquiring Stronghold Keycards, since the alternative involves fighting off Mercenaries found in Mercenaries Camps and looting an RNG Loot Cache.

There is an infinite supply of Stronghold Keycards at Buy Stations, so this method is repeatable if you die or for future objectives too.
