Logic Master Key Systems Get New Numbering Scheme

May 6th, 2013

The Medeco eCylinder Team announces that continued progress towards process flow improvements for Medeco’s CLIQ products, Medeco Logic and Medeco3 Logic, has brought about a recent change in how Medeco creates new electronic Master Key System numbers. Historically listed and referred to as “CL” numbers, Medeco Logic electronic systems will now start with “US”.

Any systems created in the CL150 method are not affected and will continue to be able to add keys and cylinders to their current electronic MKS.
