Disclamer : This is a bone-lazy (not sure about this word) idea, take it serious or not..
If you are owner of a world, and if you clear your inventory but you had a keycard, you have to rebind the keycard etc...
If you are owner of a server, and you want to bypass a door, you have to go in spec and then bypass the door and then go back to the previous mode, it's long.
So there are two possible possibilities :
-
A command : You type something like /bypass, and when you shift + click on a keycard reader/keycard lock, it opens the door
-
An item : You have an item in the hand, and when you shift + click on a block, it opens the door
