I've never seen the handle locking mechanism, but is the hole directly against the J1772 handle body so that if you stuck a rod through it, the rod would be practically rubbing on the handle body? Cause that's what's supposed to prevent the trigger from depressing: a thick lock that rubs against the handle.
Did you make sure the lock you had was just barely thinner than the hole in the handle? If the lock's loop/shackle is thin enough, you could still press the trigger down to unlock the handle from the J1772 port on the Bolt.
