ignition lock cylinder

So I bought a 2000 s10 with a 4.3 vortec and the ignition crapped out sometimes took 15 min of wiggling the key to turn it. So I bought a replacement. I have gone through all the steps all the way up to removing the cylinder. The problem is I can get the cylinder about a quarter of the way out...

Just picked up a 2001 S15 (4.3/auto/2wd) that'd been sandwiched front and back in a wreck, but only cosmetic damage. I drilled out the ignition lock and replaced it with an AutoZone Dorman one, so that's new. I hooked up my battery charger to goose the battery and see if it'd crank. Everything...

Video below pretty much explains my situation. To summarize, I got a smokin' deal on a nice 1999 S10, due to someone trying to steal it from the previous owner, and screwing up the lock cylinder in the process. Previous owner wasn't mechanically inclined, so he sold it for next to nothing...
