• How do I change the master code on my Sargent and Greenleaf electronic safe lock?

  For many S&G models like the 6120, begin by pressing SG* (74*), followed by the existing six-digit master code and #. The lock will beep five times. Next, press 1* followed by your new six-digit code and #. Enter the new six-digit code again and press #. Always leave the safe door open while testing your new code.

• What does it mean if my Sargent and Greenleaf lock beeps 20 times?

  If you enter a code and the lock beeps twenty times rapidly, the battery is low and must be replaced. The lock generally uses a 9-volt alkaline battery (Duracell is highly recommended).

• What is the factory default code for Sargent and Greenleaf locks?

  The factory default master code for most S&G electronic safe locks is 1 2 3 4 5 6 #. For security reasons, you should set the lock to your own unique master code immediately upon installation.

• What is the time delay feature on an S&G lock?

  A time delay is a security feature typically used to deter armed robbery. It requires a waiting period (e.g., 1 to 9 minutes) between entering a valid code and when the lock actually opens. Users must enter their code again within a specific window after the delay completes.
