This addon adds 16 new doors to the game which can be locked/unlocked using special key cards, you can either set these doors to get unlocked only by you or by anyone with the key card. You can even use these doors in any of your maps or templates.
These doors when lock are unbreakable which means that they neither burn, drown, fished, brake nor can be killed (You can use /kill but still it won't die, when locked ). They can only be unlocked by the same colour key cards (The default/normal door only get's unlocked/locked with normal key card). You can even name a door using name tags to remember or make a map using this addon.
