Changing Batteries—Two-Battery Keypad
Step 1 —Remove the keypad from its mounting base. This can be done by pulling the bottom of the
keypad housing away from the base (photo 1). Grip the keypad housing as shown in the photograph for
best results. Support the keypad housing so that the wires which are attached to its circuit board are not
pulled or stressed. Do not let the keypad hang from its wires.
Step 2—Turn the keypad over and remove both batteries. This is best done by grasping the bottom of
a battery and pulling it gently away from the keypad circuit board. Do not use any type of tool to pry a
battery from its holder.
Step 3—Install new batteries by pushing them directly into the battery connectors attached to the
keypad circuit board. It’s important to support the connectors so they will not get bent during battery
insertion (photo 2). The connectors are designed to make it very difficult to install a battery incorrectly.
Pay close attention to battery polarity so as not to damage a connector by forcing a battery into it
backwards.
Step 4—Hold the keypad housing close to the mounting base while you coil excess wire inside the
housing (photo 3). Position the wire away from the spring clips that hold the keypad housing to the
mounting base.
Step 5—Align the spring clips with the receptacles in the base. Using steady pressure, push the
keypad housing back onto its mounting base. Don’t allow any wire(s) to be damaged by contact with the
spring clips. The keypad housing will snap into place on the base.
Step 6—Check the master code and all user codes at least three times with the safe door open. Close
the safe door only after the lock has been thoroughly checked for proper operation.
Note: The 6120 will operate with just one 9-volt alkaline battery attached to either connector. This is only
recommended under emergency conditions when a second replacement battery is not available. Using a
single battery will not harm the lock in any way.
Changing Batteries—One-Battery Keypad
Step 1 —Keypad disassembly is neither required nor advised. The removable battery holder is
accessed from the bottom of the keypad base. Pull it slightly toward the front of the keypad, then
downward to remove it (photo 4).
Step 2 —As you remove the old battery, you will notice there is a spring at the bottom of the holder.
The new battery will rest on top of this spring to maintain good electrical contact.
Step 3 —Note that the battery is oriented so that the larger contact is in line with the larger opening
in the top of the battery holder (photo 5). It’s important to orient the new battery this way.
Step 4 —With the new battery in the holder, slide the holder into the base of the keypad until it clicks
into place (photo 6). If your lock does not operate properly, don’t press any buttons for five minutes,
then try it again.
