Warship Keycard

The Warship Keycards or in full Tekunin Warship Keycards are access cards belonged on the Tekunin Warship built by the clan of cyborg ninjas known as the Tekunin. They first appeared within the Konquest mode of Mortal Kombat: Armageddon, though one of them is called Sektor's Keycard since it is belonged to the Tekunin clan's leader Sektor who commanded his warship

This card can open any door on Sektor's Tekunin warship. If he catches the one who stole it, they can surely expect a swift, and painful, death.
