I/C Pin Diameters

There have been some locks that used odd-sized pins. I'm not sure if any of the ICs fall into that category...

What I am mainly asking about is BEST SFIC. If there are different diameters, then you would have to have a different core in order to repin it from A3 to A4.

If it's Best versus Best... then I agree, the statement that pin diameters would vary sounds like someone's confusion.

I can hear the company rep right now-"No, You can't repin those spare cylinders.They have different pin diameters.We can set you up with new ones.You can use your A4 pins in these juuuust fiiiiiiiine."-LOL

I'll admit I don't know this total sure. My guess is that the A2 through A4 refers to the depths on the keys (and the lengths of the pins). Not the diameter of the pins.

I'm expecting to be corrected about this.

NOT having my book handy and not doing enough to have it memorized it refers to the 3 DIFFERENT dept of cut spacing used on the keys, which also relates directly to each pin HEIGHT diameter of the pin is all the same, as is the pin to pin spacing. to totally do IC, requires 3 pin kits for Fest, plus Falcon, plus how many others i dont know of hand, as i SELDOM see one in my neck of the woods, and when I do its on a 'company supplied' door.. like Sonic, and Freds-they got their own locks, and the regional manager has necessary cores when needed.

Shiva, I'm thinking the same way you are. I'm not talking about anything exotic. Standard Interchangeable 6-pin cores. KSP or BEST

Thanks, goma.

here is the pin lengths..LOL

Yes!!!!!!! I was right-I will be sure to tell him.

Hmmm-I could use one of those...

Thanks again Shiva!

Best A2 system may have the most depths available, but it requires two-step progression in designing the keying systems... So when a core is combinated to a TMK that only leaves

A3 and A4 can utilize single-step progression when designing keying systems... So therefore even though they have fewer depths available they can create systems just as large or even larger than an A2 system can...

A3 for instance can have a TMK set and then still have 6 depths left to progress keys...

One word of caution about the color-coded lab pins for A2 systems -- they are a security risk as someone can eyeball the core without much tampering and if they know anything about lab's color coding scheme they can cut a key that will open at least that one core...

NOTICE they are 108 diameter instead of the 115.. --Shiva--

Yep-I saw that.

Later, goma.

The genuine Best SFIC has pins of exactly the same diameter whether they use the A2, A3 or A4 increment. That pin diameter is different from what is normally used in non-IC door hardware. Typically door hardware pins have a .115" diameter while Best SFIC pins have a diameter of .114". In that tighter tolerance IC with its smaller diameter plug, etc. that is an important difference. maybe he misunderstood and though you wanted to use a non-IC pin kit. BBE.

Eyeing the color coded bottom pins only gives you a change key.

Actually that is not always the case, you will get a key that will operate THAT core only, [or cores that are keyed EXACTLY the same way] which will have the shallowest bittings of all the operating keys...

A properly designed master key system will have a mixture of high and low cuts on the master and change keys, otherwise if the change keys had ALL of the shallow cuts any key in the system could be re-cut to become a master...
