I have a regular-looking keyed entry handleset on an interior door. Rather than replace it with a passage lock, I decided to just take the pins out of the cylinder and have a free passage lock.

Then I looked for the release some more. Then I did it again.

...so at this point I've put it back on the door so my wife can use the door, but I still need to take it apart at some point just to prove that I can. =D
Any ideas? I'm puzzled, because like I said, I rekey the occasional lock for customers at work, and every door handleset I've ever seen had either a hole or tab-style button to press to release the cylinder from the handle, or it had set screws.
This is not some fancy schmancy lock either... it looks cheaper than kwikset.
There is one more oddity, which may or may not be relevant... when picking this lock, if I put tension on and set pin #5 first, the lock pops open sometimes before I set any other pins. (Yes, it has 5 pins in there). That seems broken to me... but the last time I picked it I had to set all 5, just like a normal lock.
