Bumped a Best SFIC

[devildog]

I'm getting much better at this bumping thing (I had an epiphany last night and it just all of a sudden started to work), and so far the victims are several Schlage mortise cylinders (C keyway, but I've got an E I'm going to try), a cheap Master no. 3, and now a Best SFIC mortise.

The Best was really not that hard--I imagine that's because it's master pinned, but only to one level (there's just one master key, no GMs, GGMs, etc.) so that didn't have THAT much to do with it--imagine how easy it would be on facilities that use Best and have multiple master key levels (and there's so FEW of them *cough* ). God, almost every business I've seen either uses Best, Falcon, Arrow or something cheaper (kwikset, schlage, etc) .

The only exception I've seen is Best Buy--Medeco SFICs !! Good for them. I mean, they've only got a COUPLE MILLION DOLLARS worth of brand new, high end, electronics inventory in each of their stores--who would want that junk ?

Anyone else bumped some SFICs? Which ones are easier? I would imagine Best bumps..hehe...the 'best' because they're generally better quality than falcon or arrow so they probably have higher tolerances.

Did you get the control or operating shearline on the Best?

[devildog]

Operating shearline.

That's the one that you're most likely to get if it's master pinned (what Best locks aren't? ), and if it's not then it's a 50/50 tossup between the operating and control shearline, as those are the only two shearlines there are, whereas masterpinning creates many additional operating shearlines thereby exponentially increasing the odds of hitting one of them instead of the control for each additional master level...I think --someone better at math and more familiar with master keying than me run the numbers, please, or give a better guesstimate than I just did .

Anyways, point is master keying creates a whole bunch of additional operating shearlines for you to find, thereby making bypassing the lock by picking or bumping that much easier for you . If there's no master pinning then there's one operating shearline and one control shearline, so the odds of hitting either one are 1 in 2, but if there's master keying that creates, say, 10 operating shearlines total, then your odds of hitting the control just went from 1/2 to 1/11 (10 operating + 1 control) and your odds of hitting an operating shearline are now 10/11.

I'll have to try some bumping ... I need to bring my vice from home, so I can mount some of the best core'd padlocks I have sitting around for bumping. Good to hear that it works pretty well! ~Grit.

[keysman]

Yes it works well .. about 50% of the time I get the control


On the medeco SFIC , if that is Keymark .. it is just like any SFIC no angle cuts , no sidebar

if you can get a key thet will fit in properly . you can bump it

OH BTW
SFIC = small format Interchangable core

A guy brought in an Abus 83/55 that was locked onto a chain (he had lost the key) and wanted some keys cut for it. First things first, the workshop techs had to get it open. Hand picks, no luck. Pick gun, nothing. Out come the bump keys. Two bumps and she was open.

lol..

Abus are so defenceless when faced with a 999 as the opposition

But it starts to laugh when the HPC's are pulled out

Hehe, true true.
