 Purchase for 2,000 at Buy StationsFound in Mercenaries Camps |
Buy at Buying Station
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.
Look for shopping cart icon to find Buy Stations

How to Use Stronghold Keycards
Unlocks Mercenary Strongholds
Use the Stronghold Keycard to open the Mercenary Stronghold, which would otherwise be locked. Prepare for a fight, however, since the Strongholds contain lots of Mercenaries that will immediately open fire on you.

 Strongholds |
If you're doing the Infiltrator mission, you'll need to open a Terminus Outcomes Stronghold after acquiring the Stronghold Keycard. A Terminus Outcomes Stronghold is no different from any other Mercenary Stronghold, so just look for the nearest one on the map.
