摘要

A key device (10) includes a generally elongate shaft portion (12) including a key combination surface (16) that has a plurality of key cut stations (18) for forming telescoping key cuts at each key cut station (18). Each key cut station (18) has a telescoping maximum adjacent cut specification (MACS) that defines a maximum depth of adjacent. The key device (10) also has a non-MACS key cut (20), formed at one or more of the key cut stations (18), for interfacing with a first pin (24) of a given telescoping plug pin. The non-MACS key cut (20) is dimensioned to leave material in the elongate shaft portion (12) for forming another key cut (20A) for interfacing with a second pin (26) of the given telescoping plug pin.
