9V Batteries in Electronic Lock

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.

• 2 Signs that the Batteries Needs Replaced!
• 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

FACT: The circuitry is designed to hold the password information for extended periods of time even if there are no batteries installed.

Many safes today come standard with battery powered or electronic locks. There are many reasons to buy a safe with either a digital keypad or biometric fingerprint sensor; whether that be security, safety or access control.  In today’s blog post we will walk you through the standard procedure for replacing the battery in the S&G® 6120 lock. You’ll know that it is time to put in a new 9 volt when the lock beeps repeatedly when not in use.

The Sargent & Greenleaf® lock is standard on many commercial fire safes. Manufacturers such as FireKing,  SentrySafe and Hamilton utilize these locks for reliability and access control.  After continuous use, the battery will weaken and replacement is necessary. Typically the battery life for a safe with electronic lock is one year or more.

Low Battery Condition
The Model 6120 lock uses two 9-volt alkaline batteries. S&G® recommends Duracell®. If the batteries in the lock need to be replaced, a total of twenty consecutive beeps will be audible after the last number of the code and the # sign have been pressed. The batteries must be replaced before the lock on your safe can be opened.

Step 1—
Remove the keypad from the mounting base plate. This is easily accomplished by pulling the bottom of the keypad away from the base. Grip the keypad as shown in the photo for best results. Support the keypad so that the wires which are attached to its circuit board are not pulled or damaged. Remember, do not let the electronic keypad hang from its wires!

Step 2—

Turn the keypad over and remove both 9 volt batteries.  This is best accomplished by grasping the bottom of a battery and pulling it gently away from the circuit board.  Please do not use any type of tool to pry a battery from its holder as this can cause damage to the locks circuit board.

Step 3—

Install new 9 volt batteries by pushing them directly into the battery connectors. Again, S&G® recommends two Duracell 9 volt batteries. During this step remeber to support the connectors so they will not become bent or damaged when insterting the new batteries. The connectors are designed to make it very difficult / nearly impossible to install a battery incorrectly.  Pay attention to battery polarity so you don’t damage a connector by installing a battery backwards.

Don't Damage the Wires!

Step 4—

Hold the electronic keypad close to the mounting base while you coil the excess battery wire inside. Gently move the wire away from the spring clips that hold the keypad to the mounting base – this will again prevent damage to the electronics and circuit boards of the  lock and ensure proper operation of the safe.

Step 5—

Align the spring clips with the in the base. Gently push the keypad back onto its mounting base. Don’t allow any wire(s) to be damaged by contact with the spring clips. The keypad should gently snap into place on the base.

Step 6—

Check the master password and all user codes (if you have them)  at least three times with the safe door open. Close the door of the safe only after the lock has been thoroughly checked for proper operation.

Failure to check the lock prior to closing the door could result in the inability to open the safe. If this occurs, a locksmith will need to be called to open the safe, creating costly expenses (especially if it’s after hours or over a holiday).
