Schlage C
on Keyzee.
Schlage C is the standard 6-pin keyway in the US — non-restricted, blanks readily available at any locksmith supply. Used everywhere because it's cheap, the depth spec is forgiving, and most US institutional master key systems started life on it before being upgraded to Primus or Everest.

What Keyzee does for Schlage C
Schlage C is a first-class profile in the engine — the same TMK optimiser, phantom scan, MACS validation and export pipeline runs against Schlage C cylinders as against any other. No add-on, no separate licence.
Factory MACS + depth specs shipped
Schlage C's MACS, increment table, and pin-stack constraints are built in. Every TMK candidate is validated before grading.
Phantom scan, exhaustive
Up to 50,000 shear-line combos per Schlage C cylinder, run against the full access matrix. Critical / high / medium classified inline.
Code-machine exports
Schlage C cuts ship as InstaCode (.ick), Genericode (.gcd), Silca KD (.skd), CSV and PDF — directly into Silca Futura, HPC CodeMax or Framon.
Restricted-keyway handover
Every Schlage C system exports a compliance handover record — system ID, signatories, your locksmith licence, full key register, customer signature block.
