Arrrgghhh! I hate this center justification!

Sorry... anyway it is because
there is no trap door, or cylinder retainer houseing. There has to be a place for the
bible to come out with the cylinder, or 90 percent of the time it has a retaining
pin holding the plug in and the shell and bible are the body of the padlock. Many times the
cylinder retainer houseing will be held in by a retainer screw found inside the bottom
of the cavity of the opened shackle. If there is a screw in the bottom of the
cavity, then turn it and the houseing and cylinder will be release. Trap doors are this way
as well. However, on occasion trap door's will be swaged in, which means it looks rekeyable,
but the trap door cannot be removed from a retaining screw. There are of course other
ways to hold a cylinder in a rekeyable lock, but these are the most common ways.
