subject: mAnAgement reset code (mrc)
Models 6120 and 6123 can incorporate a Management
Reset Code if one is programmed before the Factory Master
Code is changed or reset. Once the Master Code changing
procedure is completed for the first time, a Management
Reset Code cannot be installed. Once programmed, the
Management Reset Code cannot be deleted or changed.
Sargent & Greenleaf strongly recommends that a different
Management Reset Code be used for each lock.
The Management Reset Code consists of seven digits.
For added security, two of the digits must be pressed
simultaneously. These digits must be either 0 and 1, or 0 and
3. They may be used anywhere in the code. For instance, a
Management Reset Code could be 1 4 7 [01] 8 9 (0 and 1 are
pressed simultaneously). To use the Management Reset Code
in this example, press:
*
6 # 1 4 7 [0/1] 8 9 #. The lock’s
Master Code will revert to 1 2 3 4 5 6 #.
Immediately after the Management Reset Code is entered,
the lock will beep once for each time the MRC has been used,
including the current usage. This simple device is provided to
let the safe operator know how many times the Management
Reset Code has been used to reset the lock. The Master Code
is now reset automatically to the original Factory Master Code
(1 2 3 4 5 6 #). Any User Codes which were present in the lock
when the Management Reset Code was entered will be erased.
6120 Lock—If a time delay was being used, it is eliminated.
6123 Lock—If a time delay was being used, it is still
present. The lock will also retain its mode of operation (single,
dual user, or supervisor/subordinate mode), and the time delay
override code if one was set. After using the MRC, it may be
necessary to use the master code (123456) to create user
codes in order to operate the lock if it was set to dual user or
supervisor/user mode.

Note: The lock will not accept a Management Reset Code
when it is in lockout mode. To be certain your lock is not
in lockout, leave the keypad connected (with batteries
installed), and do not press any buttons for a minimum
of 15 minutes. Then enter your Management Reset Code.
