There is a hidden path in a wall ;)
You need to jump to the left from the platform with the door, the key is there.

Further use flashings to find these hidden doors

Armund is right there are secret walls that you can go through to find keys that unlock the gates/doors. Unfortunately the flashing doesn’t actually show the secrets. It’s just an effect I thought was cool haha. In the future I might change that and add it in though because it seems like that’s what most people think is going on.

Thanks for playing!
