## Most critical reviews (3 lowest-rated)

### 1/5 — Corbin LFIC

*2025-10-06*

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

### 1/5 — Does not work in all situations

*2015-10-13*

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

**Developer response:** 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.

### 5/5 — A "must have" for Facility Locksmiths!

*2013-06-20*

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.

**Developer response:** So glad you like! Thank you for your kind words!
