Mul-T-Lock Classic
on Keyzee.
Mul-T-Lock Classic uses a telescopic pin-in-pin design — each chamber has an outer and inner pin, both of which must lift to the correct depth simultaneously. Effectively doubles the chambers without changing the cylinder size. Patent-protected blanks make blank acquisition controlled.

What Keyzee does for Mul-T-Lock Classic
Mul-T-Lock Classic is a first-class profile in the engine — the same TMK optimiser, phantom scan, MACS validation and export pipeline runs against Mul-T-Lock Classic cylinders as against any other. No add-on, no separate licence.
Factory MACS + depth specs shipped
Mul-T-Lock Classic'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 Mul-T-Lock Classic cylinder, run against the full access matrix. Critical / high / medium classified inline.
Code-machine exports
Mul-T-Lock Classic 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 Mul-T-Lock Classic system exports a compliance handover record — system ID, signatories, your locksmith licence, full key register, customer signature block.
