kwikset ultramax core (attn. GC )

[awol70]

well here is the core,with the offset holes..my best guess is that the holes are designed to catch a BB,or a tapered pin tip.
like a construction core.
notice the keypins are flat,like drivers.
the holes are also a slightly smaller diameter than the pin chambers.
my theory would add up.

That core looks sweet

Most of the Kwikset cores around here all have those offset holes, they tell me it is for construction keying, a place for the bbs to go, but who the hell knows!

I've been told that the holes are there beacuse they took that mettle out so they could make more cores by melting it down so they spend less money

BZZZT, wrong

Construction keying. Builders keys have a lower cut in one or more chambers than the owners key.
When the owners key is inserted, with a higher level cut, the construction ballbearing\master pin is raised into the bible, falls into these holes, and stays there for the life of the lock.

Some brands use smaller (circumference) master-like pins, most use tiny ballbearings.
For instance, Gainsborough use master pins which fall into these holes.
Lockwood use a ballbearing that is equivalent to 4 depths.

The coolest I've seen so far is Dexter, which used a donut-shaped master wafer. The corresponding hole to receive it has a pin in the center, reminiscent of security head screws.
