Corbin LFIC

I need to do a L4 Corbin LFIC with 4 change keys can you add functionality for multiple change keys in the app ?

Does not work in all situations

Does not work if your master key cuts are deeper than your control key cuts, returns negative pin numbers

Response from developer

If you're referring to Corbin Russwin (both sys70 and non-sys70) you will indeed return negative pin numbers any time the control bitting is less than a master or change bitting. This is how the these systems were designed. If you would like more information or need any help feel free to contact me.

A "must have" for Facility Locksmiths!

Phillip D., you keep making incredibly useful apps in for the locksmith community. If you have a Sargent or Corbin large format system then you must get this. I encourage everyone I train on buying this app.

Response from developer

So glad you like! Thank you for your kind words!
