The GMS R118SC3A2 is a keyed-alike rim cylinder designed for use in rim-style lock applications on commercial and residential doors. The cylinder features a Schlage C keyway and ships keyed alike to the K2 combination, making it well suited for facilities that require multiple locks to operate on a single key. At 1-1/8 inches in length, it installs directly into standard rim exit devices and night latches. Licensed locksmiths and commercial door hardware technicians are the primary installers. The bright brass finish suits applications where a polished, traditional appearance is specified.
This cylinder is used in rim lock applications on wood, hollow-metal, and aluminum-framed doors in both residential and light commercial settings. It is a common replacement or retrofit component for exit devices, deadbolts, and rim latches that accept a standard rim cylinder format. The Schlage C keyway makes it compatible with existing Schlage C keyway key systems, simplifying key control on sites already using that keyway family. It is sold individually and is also available in case quantities of 10 for larger projects or service stock.
Designed as an OEM-style replacement rim cylinder for rim exit devices, rim deadbolts, and night latches that accept a standard 1-1/8 inch rim cylinder format with a Schlage C keyway.
Installation is typically performed by a licensed locksmith or qualified door hardware technician. Before servicing, ensure the door is secured in an open position and all connected hardware is disengaged. Standard cylinder removal tools and a screwdriver are generally required. Follow local building and fire codes regarding exit device hardware when replacing cylinders on egress doors.
