CRL KMK4 Keymatic Number 4 Combination Key for Keymatic Series Locks

Keymatic Locks combine high security with the ability to select eight different keys to operate each lock. The Master Combination Key allows you to change the Lock to accept any one of the eight keying combinations. This lets you change combinations between shift changes, or in cases where a key might have become lost or stolen. The quick combination change maintains security with no lost time for Lock replacements.
Each 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, 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).
