First off, if you tell us the type of lock it would help. In normal deadbolts, you'll probably have to pry to chamber cap off and load the chambers that way. You say that you've taken all the pins and springs out, so you'll have to do the above, whereas if you had used a plug follower, you could have kept the driver pins and springs inside the cylinder (top chambers) and re-pinned the plug (if that's what you were intending to do... re-pin)
If you don't know what a plug follower is or how it's used, go here:

The second last post from cracksman is an especially good site.
Hope this helps. Post with more info and an update.
Sorry....
