Disclaimer: This is an edited version of a already existing previous security door uploaded by the youtuber Mumbo Jumbo


In 1.11.2 some minecraft security doors already existing have become obsolete,or useless. So I tinkered around with the design and made some small changes to fix up the design to work in 1.11.2. I've decided to upload this in case people want to see one way of how to fix the minecraft security key card doors. If you don't know what i'm referring to, basically it's a door that only accepts one type of item to open the iron door/activate the redstone device. If the "key" is a renamed anvil named 'keycard' then only anvils with that name will open the door. That's a quick run down on what a keycard security door is. Anyways hope this is useful to people.
