High Security Bottom Pins

[Wolf2486]

I know the technique to picking high security driver pins etc, spool, serrated, mushroom, but how do you go about picking high security key pins? Any information is greatly appreciated.

Have you seen these somewhere? I wasn't aware they existed, being under the impression that they could be bumped out of place easier. That's particularly true with a mushroom pin on the bottom...

[Wolf2486]

Yeah, I have a Corbin lock with bottom pins that are spooled at the top. Serated bottom pins are also popular in Yale and in some Mul-T-Locks.

yeah - varjie sends some serrated bottom pins with his kit I think... I've got some anyway..

so I can pick a schlage with all serrated bottom pins as easily as with no security pins - just don't overset them their annoyance comes when there's a serrated top pin too - making it difficult to figure out where you're at.

[Wolf2486]

just don't overset them

Easier said than done. Anyway, say we are all not little WhiteHats , is there any way to go about unsetting the bottom pins?

If you're picking the normal way serrated bottom pins don't make
any diff. It's only if youre reverse picking that they matter.

Chances are that if there are high sec bottom pins there are also high
sec top pins tho.

Yes there are high-security top pins. Spooled bottom pins are a problem picking normally, because odds are you'll overset one and easing up on tension will unset ALL the pins.

[rakemaster]

no what I meant in my reply was that chances are if there are high
sec bottom pins in a lock, that lock also has high sec top pins.

obviously i know that high sec top pins exist. so did the orig poster, i'll bet.

[Wolf2486]

I am the original poster. I was saying that there are high security top pins in the lock I have along with the high security bottom pins. Sorry I did not state that clearly.

I tried single pin setting an american padlock yesterday, and after a few minutes, I gave up and opened it with a bogota rake in about three strokes, then I took it apart to fit a key, and noticed that the bottom pins are serrated too. I had never noticed this before, its been a while since I had to make a key the easy way to one of these, (easy, dissasemble, more difficult, time and effort, impressioning) Now I'm wondering if all american padlocks have serrated bottom pins. I always understood that the top pins are serrated, but now that I see the bottom ones are also, it makes more sense to me what mattblaze said about decoding them by using the serrations as measurment units, while using an otoscope and pin lifter to see them.
