This is a Sargent I-Core and it is giving me a hell of a time.

Any tips, help, or information would be greatly appreciated.




thanks

ok, sargent IC's work on a different principle than regular (Best,Falcon)
IC locks.
in the case of the latter, a control sleeve between the plug and shell operates a control lug
engaged by a separate shearline than the operating line,and requires a "control key".
in Sargent IC ,the control key engages two or three control pins,raising them to a point where
they engage the retaining lug,allowing it to rotate.
i have never held one of these personally,and i am just passing on MY understanding of how these locks work.
that being said, to pick it with the object of removing the plug,you may have to raise the last few pins to a higher point than the operating shearline...
as i find more info,i will update you...

o so like the corbin russwin core that i have here

thanks for your help

The Sargent core is retained by a two-pin lug (pins 3,4). The new style is 6-pin. Not real sure, but it looks from your photo as if you have an LG keyway. The control picks to the left to remove. Raking works best for core removal. If you want, you can mail the cylinder to me and I'll remove the core and produce the working keys and mail it back. (I'm a removable core expert).

No, it is quite different in operation from the Corbin/Russwin.

i have a 1/2 dozen keyless best paddys,with a few more on the way..=)

do tell?

i will think of that i need to gather more information on this lock also.

oh and by the way when i try to pick it clockwise none of the pins bind
when i pick it counterclockwise the pins bind. also the retaining lug is on the left side instead of the right side. so to pick it to the control line you need to pick it counterclockwise instead of clockwise.

Are you asking, or just mocking?

no, i would not do that..
i am genuinely interested in learning what you know.
please teach me how the Corbin-Russwin works? =)
i have lots of keyless best locks,(most i have picked to Ctrl & pulled the core)
and,I personally am totally intimidated by complexities of the operating internals,
and have neither the tools,nor the skill/knowledge to take them apart and key them
etc, yet...

as you can see the core is removed CCW


There is only 1 cut that is the same between the operator key and the control.

I can easily pick this lock but I don't know how to tension the control. If someone has info on that post it here or pm me.

awol

i have the tools to rekey best maybe we can work out a deal

What you're holding in the photo is a construction core. Unlike BEST, who color codes their construction cores, Sargent merely provides thiers unfinished (dull brass and bronze), and dimples the plug faces.
