if the pins are in a circle how od i go about counting them
1, 2, 3...etc. that is generally how counting is done

. Anyway, just count the total number of pins in the lock and that will tell you weather you are dealing with a 7pin or a 8pin.
Has anyone tried the new model SO picks on ACE II locks? I have the old model SO picks and they will not fit an ACE II without modification.
