Master Keying Systems

[Self-Taught 4731]

I appreciate all your help, and I have taken it all into consideration. However, due to the age of this thread, and considering this is slightly off-topic, I have created a new thread for this situation. I pretty much just copied and pasted my first post so some of the questions in it have already been answered, but if you would like to contribute to that conversation it is located at viewtopic.php?f=23&t=59728 . Thank you for the help you have already provided, and any future contributions to this new thread that you may provide!

I haven't read all the responses so forgive me if this has been brought up already.

A wouldn't suggest using ANY cut from the GMK in and sub or CK. Say 47562 is the master, choose something like 83744 for a sub. Then your CK's could progress the last three chambers(avoiding "562"). I think this method would be called a rotating constant. If you keep the "47562" and progress single chambers, your ck will look something like "47564, 47566, 47568...

This should be avoided. Change the first two chambers for each Sub and simply progress the last three, or four chambers. A change key should never have master bittings on it. If an observant crook noticed every key started with "47", he could simply make a master key from a change key with high cuts by impressioning or possibly doing the math. You can change the first two chambers and not have to worry about multiple master pins in each chamber.

Maybe this will help http://www.sopl.us/basic-masterkeying.html
