How to get through keysystems

Ahhh, keysystems.

Difficult for new people, here's a good tutorial on how to get through them, just simply watch the video (you dont have to read what i say at the end as its obviously the right thing but feel free to do so.)

[ NOTE ]

I paused and continued the video so that you guys dont have to wait 11 seconds each page, you cannot skip the timer like i did.

Also, dont try using the key, its assigned to me.
