Opening doors is made simple. No commands! You don't even have to worry about players leaving doors open!

Players

To open a door, the player NEEDS to be in Survival Mode, otherwise the server will think they are trying to destroy the door without permission. All you have to do to open a door is:

1. Right click to "Unlock" (does NOT consume a usage from the key)
2. Left click to confirm, consuming one usage (unless the player has unlimited uses).
   
   Once the player confirms and opens the door, they will have 5 seconds to pass through to the other side before it closes automatically, so there's no chance of someone leaving it open, and a minimal chance of someone else making it through.
   
   If the player has no uses left for the key, the door will not open.
   
   

Admins

If you're an OP (or have the proper permissions), you can automatically bypass all doors by:

1. CREATIVE MODE: Right Clicking doors
2. SURVIVAL MODE: Right OR Left clicking doors.
   NOTE: As of 1.3.0, all CK doors will automatically close no matter who opens them!
