I copied this from a DIY website, good luck.

In order to turn the lock cylinder over, you have to remove it from the knob. Because you probably do not have the tools to do this, here's a way. It's tough, not easy, and could damage your lock a bit. As stated, take the lock out of the door. On the lock side, (the side with the post sticking out), you will notice a flat tab right at the bottom of this post. Using a small flatblade screwdriver, key, or anything but a knife, rotate it to point straight out from the post. From here on out, it's really difficult to describe, so bear with me. (Best if the lock is in your hands as you read this)

Next step is that you can see the post, and that little tab are above a flat plate, with tabs at both sides. (Next to the screw receivers). On the side opposite the first flat tab, insert a small flatblade next to, but under the tab on the flat plate. You may notice that there is a tab under there, extending downward. That tab is under spring tension, and can be depressed. This releases the post. With it still turned to the intermediate position from before, pull it out while depressing that spring loaded tab. When you're ready, there is more...

Now that the post is out, you may want to get a flashlight and look inside the knob you took the post out of. You should see 2 dark spring clips on the sides of the opening. (These will be little clips that are attached to the back of the lock itself, and will be on the sides, as compared to the key hole). Now, here's the really tricky part. Use the same small flatblade to insert into the opening, and move the tabs toward the center of the opening. Yes, there are 2 of them, so it's not easy. You may also notice I didn't say "PRY" them aside. This will damage your lock. Once the tabs have been released, you should be able to remove the lock from the knob. Your home free now.

Put the post back into the knob, and turn the tab toward you. This should be the unlocked position. If not, rotate it in the other direction. Double check this step, you could lock yourself outside. Now, put the knobset back in the door, and then insert the lock in the desired position. This should do it.
