1 get a set of feeler gauges (for setting spark plugs).
2 take the clip off the back of the lock.
3 push a thin feeler gauge in to the back of the lockat the top of the plug until you reach the first stack of pins.
4 use a pick to lift that set slowly while applying a little pressure to the feeler.
5 when the feeler gives a little and slips into the lock alittle that stack of pins is set.
6 repeat until they are all set.
the idea is you are pushing the feeler gauge between the driver and bottom pin (shiming it).
when you get to stacks 2&4 the gauge will slipin an stop after a small amount. this is a way of telling they are spool pins so you must pull the Feeler back a little and lift the stack alittle more until the feeler slips again. its a little fiddly but this works i use it a lot.
