What does "function locked" mean, anyway?

Karyn asked, "Replomat, what does 'function locked' mean?" The Replomat replied, "The **Hitek Replomat(TM)** model series is incapable of performing the requested functions as stated. To perform direct gender modification of living subjects, please upgrade to a **Hitek MAU Mark 2(TM)** series or better. Alternatively, a variety of transgender prosthetic, cosmetic, and accessory products may be replicated. The nearest hairstyle machine is located in the bathroom." Karyn punched Jon in the shoulder. "Ha, I knew it! And it would have if it could!"
