other entities with evidence rooms choose this lock for its versatility and ease of use. What makes this lock unique is the ability to record, manage and analyze times and dates for every time the door has been opened or closed. Companies with access control policies in place (e.g. Cash safes at retail locations) can use this information for record keeping and as information to provide to authorities if a theft occurs.  Like any electronic lock, over time the batteries become low and require replacement.

MYTH: The lock will loose the user codes during battery replacement

FACT: The lock will NOT loose any programmed user codes, passwords or settings

Electronic locks always have some way to measure the low battery, the S&G audit control lock is not different and when a user code is entered and a series of five (5) beeps occur, the 9 volt batteries are low. This is the best time to replace the batteries. If the batteries are not replaced during the onset of the beeping sequence eventually the lock will not open and you will not be able to access the safe, vault or secure room that the lock protects.

  • A series of 5 beeps occurs when the user code is entered
  • Electronic Lock beeps 20 times and the lock won’t open.

How to change the batteries

The two 9V batteries are located directly behind the touch keypad. The S&G audit lock uses two (2)  9-volt alkaline batteries. Like most safe and lock manufacturers we always recommend Duracell alkaline batteries. They last the longest and are the preffered battery for electronic safes and locks.

Step 1.

Very carefully remove the keypad housing of the lock by gently lifting the bottom edge (closest to the S&G logo) and slowly easing it off the base.

Step 2.

Carefully detach the old 9V batteries from the battery terminals. Now, insert the brand new Duracell batteries. NOTE:  Make sure you support the top of each 9v battery holder to prevent bending or breaking the battery holder.

Step 3.

Very carefully replace the keypad housing of the lock
