Hey Guys,
Just found this thread on a search and thought I'd contribute my findings. I bought this lock from WalMart last week. About a day after I got it home, I was SPP'ing it and felt something pop out in my support/tensor hand. Turns out, I apparently pressed on a pin that was deep in the plug and it actually caused it to bust out a small slug of brass from the body of the lock!
Mind you, I wasn't manhandling it either -- it was just normal, easy pressure on the pins.
Next time I inserted the key, that retaining pin (a really long one) popped through the new hole in the side, and upon withdrawing the key, the plug pulled out of the cylinder, pins went everywhere and springs were hanging out.
So, all that to say...
1) Wow, what a weird weakness -- just jam that last pin and the lock falls apart.
2) While it's billed as a "high security" lock and the back of the package says it has spool pins, my particular lock has ZERO spools. Just standard key and driver pins -- all 5 stacks.
I took it back to WalMart and exchanged. I can jiggle the new one in about 5 seconds consistently. I'm not sure if it has spools or not, since I haven't had time to SPP the new one yet. Will post back once I know more.
Just wanted to share!
