I'm about to ask a stupid question and i hope you're easy on me 
I've got a Trek Marlin 7 (Gen 2), which came with a Rockshox Judy Coil Spring Fork (although some sites suggest an air fork i don't think it is)

How exactly do i adjust the lockout? It looks like it should be hand turnable, but it doesn't turn. Do i need an allen key? Most of my riding is more cross country and as such if i'm riding uphill i definitely lose a lot of power bouncing through the front forks. I'm happy fitting a remote switch for it if it's cheap/easy enough.
Just can't seem to find anything as a guide. When i google "Rock Shox Judy Lockout" i just get people having issues.
