It allows controlled access to a facility during the construction phase, then can be removed and replaced with permanent keyway cores at project completion. Compatible with the 64-, 11-64-, DG1-64, DG2-64, and DG3-64 series removable core cylinder lines, the 6251CMK is specified by locksmiths, security contractors, and commercial construction teams when temporary keying systems are required. Its controlled-distribution status means key blanks are available only through authorized channels, limiting unauthorized duplication.\u003c\/p\u003e\n\u003cp\u003eThe 6251CMK is intended for commercial and institutional construction projects where removable core cylinders are installed in mortise, rim, or component hardware. The temporary construction master key function allows a single key to operate all cores on a jobsite during active construction. Once the owner takes possession, cores are reset or swapped to the permanent keying system. This workflow is standard on commercial builds, schools, healthcare facilities, and multi-unit residential projects using SARGENT 64-series cylinder platforms.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6-pin configuration matches the 64-, 11-64-, DG1-64, DG2-64, and DG3-64 series removable core cylinders\u003c\/li\u003e\n  \u003cli\u003eTemporary construction master key function provides jobsite-wide access during the build phase\u003c\/li\u003e\n  \u003cli\u003eRemovable core design allows fast cylinder conversion from construction keying to permanent keying without replacing hardware\u003c\/li\u003e\n  \u003cli\u003eControlled distribution limits key blank access to authorized dealers, reducing duplication risk\u003c\/li\u003e\n  \u003cli\u003e1-year limited manufacturer warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with SARGENT 64-, 11-64-, DG1-64, DG2-64, and DG3-64 series removable core cylinders.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and keying of removable core cylinders should be performed by a licensed locksmith or qualified security hardware professional.
