CRL Combination Keys provide the user with eight different combination options in addition to the Master Combination Change Key.
Each CRL Keymatic Lock comes with a Master Combination Change Key (Cat. No. KMKM), and two No. 1 Combination Keys (Cat. No. KMK1) for basic lock functions. You may change cylinder combinations with the gold colored Master Combination Key to use any of the other seven Combination Keys (Cat. Nos. KMK2-KMK8). There are four Keymatic Lock varieties (KML13, KML41GL, KML48 and KML41), and they all use the exclusive Keymatic Cylinder for superior security and wear resistance. All Keymatic Locks have a U.S. 14 brite polished nickel finish. Optional finishes are satin nickel and brite polished brass (available on special order).
