How Do I Fix the Lock on My Interior Door That Is Reversed?

Locking interior knobs typically feature a keyhole, tab or latch that only engages from one side. Both sides are often identical; if you're not paying attention, it's easy to install the lock on the wrong side of the door. If this has happened to you, or you otherwise need to reverse the knob in order to lock the door from the opposite side, you can remove and reverse the knobs without uninstalling the bolt or bevel.
