Bump (of the thread variety, not the lock variety

)
I'm very glad I found this thread. A locksmith friend of mine gave me a bag of old deadbolt locks both Kwickset and Schlage as well as door knob locks (my hobby led him to his career). The only one that has completely shut me down is a Schlage deadbolt.
It has a relatively narrow keyway and I can't get this one to pop. I do get some slight plug rotation in the counter clockwise direction but when that happens the pins seem to freeze up. I had been running under the assumption that it had some type of security pin but wasn't really sure how to defeat it and to be completely honest, I'm still not sure exactly how to defeat it.
Should my goal to be less tension on the plug while picking as to not freeze the pins when I get to the false set of the security pin? Should I be trying for the false set then removing tension to get the security pins to the sheer line?
Side note, I'm very excited to have found this place. I've been tinkering with lock picking for years but never realized there was a legitimate community out there that did this for fun. I had always kept it as a hidden hobby as I didn't want people to question my reasons for doing it assuming I was a criminal when I'm really just a guy who likes weird puzzles.
Any advice for getting this Schlage to turn for me would be appreciated. I want every lock in the bag to be unlocked before I ask for another bag of locks.
