Open door after pressed in a correct way buttons?

Hello, im looking for a blueprint so i can open a door by pressing in a correct way some buttons. I know how to open a door with a simple box trigger. Any ideas?

I managed to get a sequence i think you wanted. This sequence should be scale-able, just keep in mind the sequence you want. There might be a more elegant way to do it, but this should get you started.

Yup this is it. Thanks!
