Smart Cylindrical Large Plate Keypad

ISC-PLK

The INOX Smart Cylindrical Lock with Indicator (ISC-PLK) offers a simple retrofit solution for upgrading existing standalone digital push-button locks without modifying the door. Designed to replace common mechanical keypad locks including Simplex and Trilogy models, its larger-format trim aligns with existing door preparation to reduce installation time, labor, and overall retrofit costs.

The ISC-PLK supports multiple programmable functions—including Entry, Privacy, Classroom, and Office modes—allowing one lock to adapt to a variety of commercial, educational, and institutional applications. In Privacy mode, the lock can provide a clear Vacant/Occupied indication, making it especially well suited for commercial restrooms and other shared spaces where privacy status must be immediately visible.
