open the consol and empty its contents
stick a small screwdrive in the slot in the front of the access plate and pry upwards
remove the access plate
this is what you see
use a 12mm wrench to tighten the nut i used a crecent wrench but a 1/4" drive ratchet would work better
now just reinstall the access plate by pressing it down firmly and put all your stuff back in and your done
