How do you reset a buffalo lock without the combination?

To reset a Buffalo lock without the combination, locate the reset mechanism, which is usually a small pinhole on the lock body. Insert a thin tool, such as a paperclip, into the hole while turning the lock to the open position. Hold the tool in place, then turn the dial or handle to set a new combination. Once you've set the new combination, remove the tool, and test the new code to ensure it works.
