SCHLAGE SC4 Master Key Starter System (1 Cut Master Key, 16 Cut Change Keys)

Master key system

They went above and beyond. I realized I accidentally ordered a 6 pin master key system. I asked to Cancel because I needed 5 pin. They offered to cancel for no charge, but also offered to just make a 5 pin system for me. The key charts it comes with are unbelievable. I couldn’t be happier.
