Keyed Different (KD)
Each padlock has its own key. This is the standard for all products unless requested otherwise.
Keyed Alike (KA)
Padlocks can be opened with the same key, offering convenience and eliminating multiple keys for those who use numerous padlocks.
Master Keyed (MK)
In this system, one key can access one or more separate groups of padlocks or cylinders that are each operated by their own individual change keys. This is ideal for supervisor access.
Five– or six–pin cylinders can be keyed differently, alike, master keyed or grand master keyed, with a variety of keyways. Replaceable cylinders and shackles make these padlocks easy to service.
Factory–built keyed different, keyed alike, or master keyed. These padlocks are non-serviceable; shackles and cylinders cannot be replaced.
Door Key Compatible
American Lock’s door key compatible cylinders and padlocks mean the same key system can be used for all doors and padlocks, one key opens them all. This allows for greater key control, security, affordability and convenience.
