hey a locksmith in my neighborhood had some SC20s and i was asking him about it and wen i asked him to make one he said its a 6 pin key and only exists AS a 6 pin key....

Now my question is it indeed ONLY a 6-pin key? but then on your site for the SC20 the picture shows it as a 5-pin key... plus another thing... if it IS indeed a ONLY a 6-pin then how will it work as a skeleton key on 5 pin schlages?

and i did search around for it online.. i've only seen 6 pin ones... can anyone help me out on this one?

The SC20 is a 6 pin key but that does not mean it wont work on a 5 pin lock. The spacing of a 5 pin SC and 6 pin SC are exactly the same, the only difference is the extra pin at the end. So the 6 pin SC20 will fit into any SC 5 pin or 6 pin lock. If you put it into a 5 pin lock, not all of it will fit in, but that's fine, it will work exactly the same as a 5 pin key.

you wont be able to do the minimal movement method though, because the shoulder will not connect with the lock.

Your locksmith is correct, there are two different keys specifically for 5 pin keyways and 6 pin keyways, but as I tried explaining before the 6 pin key works perfectly fine in the 5 pin keyway. A bit unecessary, but hey, if you feel more comfortable with two keys then it's up to you.

It does seem that you need to do a bit of research on how the keys actually work www.toool.nl/bumping.pdf if you did then you would understand why a 6 pin key would work in a 5 pin keyway.

Also when starting out remember not to practice on a lock that you use often as you might damage the lock.
