Good keycard?

I'm currently in the process of building small plots on my minecraft server. But a mistake happened to me. When dividing the plots, I didn't consider that I need a keycard door. The redstone technique is too big for the free space. Now my question do you know a plugin where ne keycard door and different keycard are there? 12 keycards are required. Do you know a plugin with keycards? You shouldn't need another plugin either.

I don't think there's a plugin for it but there's a mod.

(but there are no 12 keycards)
