Emtek CY4-PSCHCTS2-US3 Schlage C Cylinder Key-in Knob Lever

Product Description

The EMTEK CY4-PSCHCTS2-US3 is a single-keyed replacement cylinder designed for use with key-in knob and lever door hardware assemblies. This cylinder is keyed to the Schlage C keyway, one of the most widely used residential and light commercial keyways in North America. It is intended for door hardware sets finished in US3, US4, US7, or US3NL, ensuring finish-matched integration when replacing or upgrading an existing lock cylinder. Locksmiths, door hardware installers, and finish carpenters typically service this component during rekeying projects, hardware upgrades, or lock replacements on interior and entry doors.

This cylinder is suited for residential and light commercial door hardware applications where Schlage C keyway compatibility is required. It fits key-in knob and key-in lever trim sets using the standard Schlage C cylinder format. The finish designations US3, US4, US7, and US3NL cover polished and satin brass and related tone families, making this cylinder appropriate for matching existing hardware in period or transitional interior designs. Each unit is sold individually.

Installation Notes

Installation and rekeying of door lock cylinders should be performed by a licensed locksmith or experienced door hardware installer. Remove all tension from the door latch and ensure the door is open and secured before disassembling the lockset. Standard cylinder removal tools and a plug follower are typically required for proper extraction and reinstallation. Verify that the replacement cylinder finish matches the existing trim set before final assembly.
