How to Program and Change battery in S&G Biometric Safe Lock

How to Install The Batteries into Your S&G Biometric Lock

We'll go ahead and install our batteries in the compartment. I've pulled one pair of my power wires out through the front of the box, the battery box, and as I install this battery, notice that I place this top end of the connector cap up underneath the bar that's at the top of the battery compartment. Now I'll repeat and do the same thing on the other side. Pull my power wires out, connect them to the top of the battery and install the battery so that the connector cap is up underneath the small bar at the top of the box.

How to Setup Your S&G Biometric Lock

Our keypad is installed, the batteries are also installed; now it's time to perform some setup functions with the lock.

  1. We always begin by pressing the start key. It says “initializing sensor.”
  2. Now it says “place finger or enter pin.” Instead of doing that, I'll press the star key and it asks for a setup code which is the master code for the lock. Our default master code from the factory is 1-2-3-4-5-6. All codes are followed by the pound sign.
  3. Now we have access to the setup menus, we can scroll through those by using the up or down arrow key.
  4. When we get to the last item that's available to us, the menus scroll around to the beginning again. We want to access the display setup functions. That's number one so we press the one button.
  5. We can select to change our language from English to Spanish and back and forth if we want to, but I want to scroll down because I'm looking for the LCD backlight feature which is item number 2.
  6. When I press number 2, now I have the option of enabling the backlight. So I'll press 1. The backlight comes on immediately, and it will stay on anytime the keypad is active. After a short predetermined amount of time of no activity, the display will turn off.

How to Set Your Lock Type on Your Biometric Keypad

Now that we have the backlight turned on we need to tell our keypad what model of lock it's hooked up to.

  1. So again we need to go back to the setup menus. I'll press star.
  2. It asks for the setup code which is the factory default code of 1-2-3-4-5-6. All codes are followed by the pound sign.
  3. We're into our setup menus. I'll scroll up or down through the options. I need to select option number two which is lock setup.
  4. And now I'll scroll down through the available options here, and what I'm looking for just happens to be the first option, its lock type. So I'll press one.
  5. This lock happens to be a model 6120 but let's look at the options that are available. It could be a Z02 lock. It could be a 6120 or it could be a 6123. I’ll select item number two because our lock is a model 6120. Now our lock type is set.

How to Change the Master Code on Your S&G Biometric Keypad

Let's go through the procedure for changing the master code on our lock.

  1. Again we start by pressing the start key.
  2. Instead of placing a finger or entering our pin code, we press star.
  3. It asks for our setup code which is the factory default master code for the lock of 1-2-3-4-5-6. All codes are followed by the pound sign.
  4. We're into our setup menu and we'll scroll down to lock setup. That's our number 2 item, so we'll press 2.
  5. We'll scroll down through the lock setup menu. Lock program, yes, we're going to change some programming in the lock which is option 2.
  6. In our 6120 setup menu, we can: enter a user, delete a user, or we're going to change the master code which is selection number 3.
  7. We can enter our new master code. I'm going to change it from 1-2-3-4-5-6 to 6-5-4-3-2-1 which wouldn't be a good master code in real life, but it's a good demo master code. All codes are followed by the pound sign.
  8. It says “confirm new master code,” so I'll need to put in my new code again. 6-5-4-3-2-1 followed by the pound key, and the keypad and lock will go through the process of changing the master code.

Now the changing process is complete. I can check that by backing up through my setup menus by repeatedly pressing the zero key until the display says “initializing sensor.” Now “place finger or enter PIN.” We'll enter our new master code of 6-5-4-3-2-1 followed by the pound sign and the lock opens. So we have verified that we have successfully changed the master code for this lock.

How to Enroll a Fingerprint on Your S&G Biometric Safe Lock

It's time for the fun part now, we're going to enroll a fingerprint.

  1. We begin by pressing the start button. It says "initializing sensor."
  2. “Place finger or enter pin.” Instead, we'll press the star key.
  3. The setup code is the master code for the lock which we just changed to 6-5-4-3-2-1. All codes are followed by the pound sign.
  4. Now we're into our setup menu and I'll scroll down using the down arrow key until I get to “fingerprint setup” which is option number 3. So I'll press 3.
  5. I'm into the fingerprint setup menu. I'll scroll down until I see “enroll,” which is option number 2. So I press the 2 key.
  6. It says “enter user ID plus pound.” We're going to associate this fingerprint with the master code which is position number 1. Remember it said to press the pound key as well. We'll enter the user code plus pound.
  7. Our master code which we just recently changed is now 6-5-4-3-2-1. We then follow that code with a pound key.
  8. It says "place finger on sensor" and you notice the green light comes on. It says “remove finger” and now it says “place finger on sensor” again. Remove finger, place finger on sensor. It takes three readings of my fingerprint to get the best possible image and it says "enrolled successfully."

So my fingerprint is now enrolled into the database of the biometric keypad. You'll note too that every time the lock is ready for me to put my finger on the sensor the green LED lights up.

How to Use an Enrolled Fingerprint on an S&G Biometric Lock

Now I'll show you how you use an enrolled fingerprint to operate the lock. It's very simple.

  1. Press start. It says "initializing sensor."
  2. The green LED comes on and it says “place finger or enter pin.” So I'll place my finger which I just enrolled on the sensor.
  3. The keypad reads my fingerprint, and then enters the code into the lock and the lock is successfully opened.

It's just that simple to operate your lock once you've enrolled a fingerprint.

At this point there are two ways I can operate my lock. I can either enter the operating code which we have changed to 6-5-4-3-2-1-pound sign, or I can simply use my enrolled fingerprint to open the lock.

How to Require both a Fingerprint and a Code

If I'd like a higher level of security, I can tell the lock to require both the code and the proper enrolled fingerprint before it opens.

  1. We begin by pressing the start key, then once the sensor is initialized, we press the star key.
  2. It asks for our setup code which is 6-5-4-3-2-1 followed by the pound sign.
  3. We're into our setup menu and we want to go to our fingerprint setup which is number 3.
  4. We'll scroll down through the fingerprint setup menus and what we're looking for is actually our first option, you notice I've scrolled all the way through the menus, that's number one mode. Do we want to use the fingerprint or pin? That's the mode we're in now. We want to select the more secure fingerprint and pin mode which is selection number 2.
  5. Our fingerprint and code mode is selected. We'll wait for the lock to cycle through, turn itself off and then we'll see exactly how this function works. I press the start button.
  6. After this the sensor is initialized. It says "place finger," so I'll do that.
  7. It reads my fingerprint. Now it says "enter user pin," which is 6-5-4-3-2-1 followed by the pound sign. Now the lock opens.

It requires in this mode both a valid enrolled fingerprint and the code associated with that fingerprint before the lock will open. It's a little less convenient but a much higher level of security.

How to Remove a Fingerprint from an S&G Biometric Lock

The next thing I'm going to show you is how to remove the fingerprint which we enrolled. Before we do that, however, it's a good idea to change the mode of the lock back to fingerprint or code.

  1. We press the star key to get us to the point where we enter our setup code which is the master code for the lock: 6-5-4-3-2-1 followed by the pound sign.
  2. We're into our setup menu and we scroll down using the down arrow key, or we could use the up arrow key and go in the opposite direction, until we get to fingerprint setup which is option 3.
  3. Now that we're into the fingerprint menus, I can scroll down until I see “mode” which is option 1; and I want "fingerprint or pin" which again is option number 1, and now it takes either a fingerprint or the code for the lock in order to get it to open.
  4. I'll back up through these menus where I'm in my setup menu again, scroll down, go back into my fingerprint setup, scroll down using the down arrow key, I'm looking for "delete," which is option number 3. It says enter the user ID and pound.
  5. We know that the fingerprint we enrolled was in position number 1, which is the master code position, so we enter 1, pound, and it asked us to confirm that user ID and press the pound sign. So I do that again and now it has removed the fingerprint that was enrolled.

That fingerprint will no longer be able to be used to open this lock, although the code associated with it can be used to open the lock. We can verify that by backing up through our menus until we come to the point where it says "place finger or enter pin" and I can simply enter 6-5-4-3-2-1, hit the pound sign and the lock opens successfully.

Remember if you have any questions or if something seems unclear to you, you can always refer back to the operating instructions that are packaged with your lock. Enjoy your biometric keypad. I'm sure you will.
