I believe it's not possible to pick a Corbin LFIC to Control

[Greygoose53]

So, I'm not a professional locksmith, as my experience was 40 yrs ago at University with a thousand Sargent cylinders in the dorms, then another 500 Corbin Jumbo cylinders in the new addition.... but then I went on to other professions. However to this day I still tinker with cylinders to figure out ways to pick them, (am stumped by those spool pins when picking) but that's getting off topic. Now that I'm nearing retirement age, I can go school and relearn that stuff.
My challenge is... looking at a Corbin LFIC cylinder, I don't think it's possible to pick it to Control level... there are no little slots on the bottom like a Best, and the videos I saw on Youtube were a joke, as the the change and control key were the same bitting. Please help me understand how anyone could pick this cylinder to Control level. A pick gun would probably always get to change key level, as there is no way to force the Control key. I dwell on logic, and I see no logical way to remove the core by picking. Hopefully someone can point out a flaw in my thinking, from professional experience. I welcome all thoughts on this.

Thanks!!!

If I remember correctly, the Corbin LFIC locks use the four middle pins for control. The first and last pins are the same as the change key. Correctly pinned, the middle four pins will all be different than the change key, though someone could feasibly have only one pin different.

Yes, they are pickable. That said, with two shear lines, it is more difficult. All pins in the control section must be picked to the same shear line in order to open (in the case of a change key) or retract the control lug (in the case of a control key).

A well combinated LFIC core will have some of the control key cuts higher than the change key, and some cuts lower, just as with an SFIC core. That would make picking more difficult, and doing key privilege escalation attacks more difficult.

I think last time I needed to remove the core from one I just drilled a little tiny hole in line with the control lug and pushed against it while using my pick gun

It is entirely possible to pick a Corbin LFIC to control, myself and many others have done it. I use top of the keyway tension and have had decent results.

Cool, I'll hafta try that on the Corbin gr 1 leverset I took off the other week

We had a bunch of Corbin levers with LFICs donated to the locksport group, we got all the cores out and I had them rekeyed with operating and control keys.

I gave it a try today, i picked it open 7 or 8 times, but every time it just opened the latch function
I suppose I will hafta drill to get the cylinder out, not a big deal as it's just an old grade 1 lever

It is possible. I've done a few. You need to get at least one of the pin stacks in chambers 2 - 5 set at control which will kind of "lock" the control sleeve in place. This will help prevent setting the other pin stacks to operating.

It's a little more predictable than trying to pick a SFIC IMO, because the 1st and 6th (and sometimes 7th) chambers is only for operating, while on a SFIC all chambers is for both operating, and control.

It's a LOT more predictable than trying to pick a SFIC
