since its rekeyable-
if you have the cylinder out in your hand, you could always use a dowel the size of the plug to follow the plug out while it is picked- holding the top pins in while you work-
then, drop the pins one at a time in a pill container, or on a soft pad where they wont roll and mix-
use a fine tip marker, sticking through the pin chambers, to mark your key blank- this will give you the location of each cut on your key-
then replace the pins in the plug. look at the first position- if the pin is not flush- take the key out, and file a couple of times on the first position- then repeat. once it is flush- move on to the next pin and repeat. once the pins are all flush- you have a working key
this is a good method if you want practice taking apart and reassembling a lock-
though if you havent impressioned much, you might want to try that for the practice
