It's your average $10 Kwikset door lock (not a deadbolt) and I've gotten as far as getting the spindle out by following these directions (<--- Kwikset's guide). However, I'm stuck on the next step (or series of steps) which is using the cylinder removal tool (which I don't have) to release the cylinder.
Here's what it looks like right now and what I've tried:

1 and 2 are the ends of the spring, and using pliars, I've managed to lock them open but that doesn't seem to do anything. I've tried this based on a thread or two I've found here as well as some googling on the subject.
3, when pressed in (downward in the picture -- it's the more silver part of the lock (which I'm sure is obvious to you fine folks)) pops 4 and 5 out further, locking around the posts. This, however, doesn't seem to pop the cylinder out, either.
At this point, I tried playing with the spring ends as well as pushing that "clip" in all while jiggling and gently turning the key.
So far as I can tell, the Kwikset guide is instructing you to lodge the removal key in the little hole that's somewhat visible in the half round cylinder, and then like a lever use the removal tool to force that clip (#3) open. I can do this with a screwdriver, but I don't seem to get anywhere.
So, would someone tell me where I'm going wrong? I feel silly resorting to this in spite of the massive resources availble, but I'm just not understanding what's being presented in other guides and threads apparently, or else I'd have this taken apart by now.
I'd appreciate any help anyone can lend. I've wanted to learn to pick for a long time now, and this is my first step to learning what in the world I'm doing.
