Hallway of Adventures - Right Door

[Wally]

Can someone please tell me how to open the the right door? I know you need to put the pegs in, but I can't find which holes to put each in. Does something need to be done before you can open the door? Or is there a button you have to press after the keys are in.

Thanks.

Thanks, it wasn't exact but it got me there. I found the right sequence (as if you were looking straight at the door) was:

x x S
x x x
x T W
x R x Ã,
