This lot includes 6 Schlage cylinders with 4 key sets. The keys are blank and turn in the Cylinders. I don't know much about locks but I'm guessing this means that the locks have not been set to any key configuration.

These cylinders are perfect for those in need of replacement parts or for those who want to upgrade their security system. The brand of these cylinders is Schlage, a reputable name in the industry.  Thank you for considering this lot for your needs.
